In Jan 2011 the Global Alliance for Vaccines and Immunizations (GAVI) and its partners are rolling out a new vaccine to prevent pneumonia in Kenya. In the developing world, pneumonia kills in the neighborhood of 1.4 million kids every year. Pneumococcal, the deadliest strain of that illness (and a major cause of what we might call “regular” pneumonia), kills 800,000.
Kenya's pneumococcal vaccine's official launch date is Feb 14, but we were able to photograph a clinic near the Kibera slum in Nairobi that already started providing the vaccine this week.
This health center is the Langata (sometimes called Kibera) District’s regional distribution center for the 36 clinics within the district. They collect all of the vaccines from the Regional Disbursement Center and, since they must maintain the cold chain to ensure the efficacy and safety of the vaccine, haul them back to Langata in well-used, white Styrofoam coolers. There, they are stored in an upright, avocado green refrigerator. But, it works and that’s what counts. They are then divided up and dispersed to the 27 clinics in the District that have trained personnel to give the vaccines.
We visited this boy during a Pulse Polio round in North Dinajpur (West Bengal, India). He had fever and a rash. His parents had refused vaccination. They agreed to give it a few days later when he got better. We discovered that they had not given him Measles immunization. The boy's father Niranjan Mistri is an expert traditional craftsman. He later prepared a wooden statue of a mother and child which is on display at the local health sub centre.
Measles immunization was uncommon in the 1960s and was only introduced in India after 1985. Todat it is helping to save the lives of hundreds of children in India.

Fatoumata Traoré and her 9-month-old son Magassoula. Since 9 August, Guinea has recorded 8 cases of poliovirus variant 2 (PVDV2) polio. In response to this outbreak, UNICEF, through the Global Polio Eradication Initiative (GPEI), is supporting the Government of Guinea in its response to the epidemic by launching a series of 3 national immunization campaigns.
UNICEF, WHO and GAVI went to Siguiri on 8 September to join the Ministry of Health in launching the first round of National Polio Immunization Campaign (Round 0) in Guinea. The first round (Round 0) of this immunization campaign targets children aged 0-59 months, an estimated 582,159 children in the Siguiri health district, as well as in the 4 neighboring districts of Siguiri, including 3 in the Kankan region (Mandiana, Kouroussa, Kankan) and 1 district in the Faranah region (Dinguiraye).
In Siguiri, Dr. Mamadou Péthé Diallo, Minister of Health, and UNICEF symbolically vaccinated a few children in front of communities and the media, officially launching the national immunization campaigns and urging parents to have their children immunized against polio, while reminding them that the vaccine is free, safe and effective.
UNICEF in Guinea participates in the implementation of immunization campaigns, supports routine immunization activities and health services, provides vaccines and logistical support to ensure that vaccines reach all children, even in the most remote areas, and supports awareness raising and community mobilization.
The second round (Round 1) is scheduled for September 22-25, 2023 and will include all 38 health districts in Guinea. The third round (Round 2) is scheduled for October 20-23, 2023, and will also include all 38 health districts in Guinea. To address the intense circulation of the virus in the West Africa region, the next two rounds of this polio immunization campaign will be synchronized with other countries in the sub-region, particularly Burkina Faso, Côte d'Ivoire, and Mali, to ensure adequate coverage of populations living at the borders of these countries.
A Fundação Oswaldo Cruz (Fiocruz) Brasília, a Organização Pan-Americana da Saúde (OPAS) e a Secretaria de Saúde do Distrito Federal lançaram o projeto Imuniza Estrutural, que busca aumentar a cobertura de vacinação contra COVID-19 e outras doenças imunopreveníveis, com o envolvimento da comunidade, em área de alta vulnerabilidade socioeconômica.
O projeto possui três pilares: comunicação e mobilização social; monitoramento e sustentabilidade das ações; e vacinação das populações mais vulneráveis.

Halima Abdi (blue/purple scarf) brought in her baby, Munira Mohamed (7 months old, she is holding her) for a measles vaccine. Also with her is her 1-year-old girl (wearing brown printed dress) who is already up to date on vaccines. She heard about the event through the outreach health workers mobilizers. She has 4 children and cares for them mostly alone while her husband moves around the town selling clothes to support the family. Halima used to clean homes in town for an income, but since the drought many people have stopped having a cleaner come as they are also suffering with less income. They lived in Baidoa but once the drought increased, they moved to Garowe where there are less people.
Nurses are working at the Jawle Health Center mobile vaccine clinic in Garowe, is set up in the Jawle IDP camp Mother and Baby center. The clinic moves to different places around the IDP camps 3 days a week so that they can reach many people. UNICEF works through EPI donors like GAVI to supports partner organizations like World Vision, Save the Children, CRC and the Puntland Ministry of Health. Many pastoralists are coming to the IDP camp here because the drought is killing off their livestock. There has been outbreaks of diseases and so this year there will be 2 rounds of an integrated vaccination campaigns (one was in March the next is in November) to immunize for measles and polio along with vitamin A supplementation and deworming.
In July there was a measles outbreak and more children for suffering but there was an outreach campaign in response to the outbreak and the situation soon stabilized. After the outreach about immunization around 530 children under 5 years old were brought into the clinic for their dose.

Immunity to the Coronavirus May Persist for Years, Scientists Find
Immunity to the coronavirus lasts at least a year, possibly a lifetime, improving over time especially after vaccination, according to two new studies. The findings may help put to rest lingering fears that protection against the virus will be short-lived.
Together, the studies suggest that most people who have recovered from Covid-19 and who were later immunized will not need boosters. Vaccinated people who were never infected most likely will need the shots, however, as will a minority who were infected but did not produce a robust immune response.
Both reports looked at people who had been exposed to the coronavirus about a year earlier. Cells that retain a memory of the virus persist in the bone marrow and may churn out antibodies whenever needed, according to one of the studies, published on Monday in the journal Nature.
The other study, which is also under review for publication in Nature, found that these so-called memory B cells continue to mature and strengthen for at least 12 months after the initial infection.
“The papers are consistent with the growing body of literature that suggests that immunity elicited by infection and vaccination for SARS-CoV-2 appears to be long-lived,” said Scott Hensley, an immunologist at the University of Pennsylvania who was not involved in the research.
The studies may soothe fears that immunity to the virus is transient, as is the case with coronaviruses that cause common colds. But those viruses change significantly every few years, Dr. Hensley said. “The reason we get infected with common coronaviruses repetitively throughout life might have much more to do with variation of these viruses rather than immunity,” he said.
In fact, memory B cells produced in response to infection with SARS-CoV-2 and enhanced with vaccination are so potent that they thwart even variants of the virus, negating the need for boosters, according to Michel Nussenzweig, an immunologist at Rockefeller University in New York who led the study on memory maturation.
“People who were infected and get vaccinated really have a terrific response, a terrific set of antibodies, because they continue to evolve their antibodies,” Dr. Nussenzweig said. “I expect that they will last for a long time.”
The result may not apply to protection derived from vaccines alone, because immune memory is likely to be organized differently after immunization, compared with that following natural infection.
That means people who have not had Covid-19 and have been immunized may eventually need a booster shot, Dr. Nussenzweig said. “That’s the kind of thing that we will know very, very soon,” he said.
Upon first encountering a virus, B cells rapidly proliferate and produce antibodies in large amounts. Once the acute infection is resolved, a small number of the cells take up residence in the bone marrow, steadily pumping out modest levels of antibodies.
To look at memory B cells specific to the new coronavirus, researchers led by Ali Ellebedy of Washington University in St. Louis analyzed blood from 77 people at three-month intervals, starting about a month after their infection with the coronavirus. Only six of the 77 had been hospitalized for Covid-19; the rest had mild symptoms.
Antibody levels in these individuals dropped rapidly four months after infection and continued to decline slowly for months afterward — results that are in line with those from other studies.
Some scientists have interpreted this decrease as a sign of waning immunity, but it is exactly what’s expected, other experts said. If blood contained high quantities of antibodies to every pathogen the body had ever encountered, it would quickly transform into a thick sludge.
Instead, blood levels of antibodies fall sharply following acute infection, while memory B cells remain quiescent in the bone marrow, ready to take action when needed.
Dr. Ellebedy’s team obtained bone marrow samples from 19 people roughly seven months after they had been infected. Fifteen had detectable memory B cells, but four did not, suggesting that some people might carry very few of the cells or none at all.
“It tells me that even if you got infected, it doesn’t mean that you have a super immune response,” Dr. Ellebedy said. The findings reinforce the idea that people who have recovered from Covid-19 should be vaccinated, he said.
Five of the participants in Dr. Ellebedy’s study donated bone marrow samples seven or eight months after they were initially infected and again four months later. He and his colleagues found that the number of memory B cells remained stable over that time.
The results are particularly noteworthy because it is difficult to get bone marrow samples, said Jennifer Gommerman, an immunologist at the University of Toronto who was not involved in the work.
A landmark study in 2007 showed that antibodies in theory could survive decades, perhaps even well beyond the average life span, hinting at the long-term presence of memory B cells. But the new study offered a rare proof of their existence, Dr. Gommerman said.
Dr. Nussenzweig’s team looked at how memory B cells mature over time. The researchers analyzed blood from 63 people who had recovered from Covid-19 about a year earlier. The vast majority of the participants had mild symptoms, and 26 had also received at least one dose of either the Moderna or the Pfizer-BioNTech vaccine.
So-called neutralizing antibodies, needed to prevent reinfection with the virus, remained unchanged between six and 12 months, while related but less important antibodies slowly disappeared, the team found.
As memory B cells continued to evolve, the antibodies they produced developed the ability to neutralize an even broader group of variants. This ongoing maturation may result from a small piece of the virus that is sequestered by the immune system — for target practice, so to speak.
A year after infection, neutralizing activity in the participants who had not been vaccinated was lower against all forms of the virus, with the greatest loss seen against the variant first identified in South Africa.
Vaccination significantly amplified antibody levels, confirming results from other studies; the shots also ramped up the body’s neutralizing ability by about 50-fold.
Senator Rand Paul, Republican of Kentucky, said on Sunday that he would not get a coronavirus vaccine because he had been infected in March of last year and was therefore immune.
But there is no guarantee that such immunity will be powerful enough to protect him for years, particularly given the emergence of variants of the coronavirus that can partially sidestep the body’s defenses.
The results of Dr. Nussenzweig’s study suggest that people who have recovered from Covid-19 and who have later been vaccinated will continue to have extremely high levels of protection against emerging variants, even without receiving a vaccine booster down the line.
“It kind of looks exactly like what we would hope a good memory B cell response would look like,” said Marion Pepper, an immunologist at the University of Washington in Seattle who was not involved in the new research.
The experts all agreed that immunity is likely to play out very differently in people who have never had Covid-19. Fighting a live virus is different from responding to a single viral protein introduced by a vaccine. And in those who had Covid-19, the initial immune response had time to mature over six to 12 months before being challenged by the vaccine.
“Those kinetics are different than someone who got immunized and then gets immunized again three weeks later,” Dr. Pepper said. “That’s not to say that they might not have as broad a response, but it could be very different.”

Temporary home to some 40,000 Kosovar refugees, Cegrane is the largest refugee camp in the country, managed by the international NGO CARE.
By end May 1999, over a two-month period, some 781,000 ethnic Albanian refugees, the majority of them children, women and the elderly, have fled the province of Kosovo in the Federal Republic of Yugoslavia for neighbouring countries -- 442,400 to Albania, 249,300 to the former Yugoslav Republic of Macedonia (FYROM), 67,600 to Montenegro, and 21,700 to Bosnia and Herzegovina. UNICEF's portion of the joint United Nations flash appeal for the Kosovo emergency is US$13.8 million. UNICEF emergency supplies being distributed to refugees include health kits, essential medical supplies, baby hygiene parcels, high-protein food, blankets, water purification tablets and water-testing kits. UNICEF's school-in-a-bag kits of basic classroom materials are being used to facilitate a return to schooling where possible. UNICEF is also assessing the psychosocial needs of children traumatized by their experiences and is working with other international agencies to trace unaccompanied children who were separated from their families during the exodus from Kosovo or while in transit to camps in other countries.
