With growing community transmission and high average mortality rates from the coronavirus in Malawi, there was widespread concern among the country’s health care advocates this week when the authorities announced that they would throw away 16,000 vaccine doses that had expired.
They were part of a total of 512,000 AstraZeneca vaccine doses that the landlocked southeast African nation had received from India, the African Union and Covax, the global initiative to procure and distribute vaccines. Health officials didn’t specify why the vaccines had expired, but said the doses went void on Tuesday “due to varying expiry dates of the received vaccine consignments.”
Health experts and campaigners warned that vaccine hesitancy, along with rumors that out-of-date jabs were being administered, might have contributed to the slow distribution of the vaccine doses and their eventual expiration.
In many African countries, vaccination campaigns have been hindered by factors like science skepticism, limited or no efforts to educate the public, inefficient distribution systems and concerns over the extremely rare but serious cases of blood clots being investigated among a small number of people who received the AstraZeneca and Johnson & Johnson vaccines. Those two vaccines, which require less stringent refrigeration, are crucial to efforts to immunize populations in poorer countries.
When the first vaccine doses arrived in Kenya in early March, there was widespread hesitancy to receive them, even among doctors, according to Dr. Chibanzi Mwachonda, the secretary-general of the Kenyan medical workers’ union. The government turned to administering the doses to nonessential workers to avoid wasting them. The Democratic Republic of Congo, which also received its first doses last month, delayed its vaccination campaign until April 19, a date it set after reporting that a task force had determined that the AstraZeneca vaccine doses in the country didn’t pose a risk to the population.
The apprehension over the vaccines also comes as the African Union stopped plans to secure the AstraZeneca vaccine — a decision one official said was made to avoid duplicating the efforts of Covax, which will still supply AstraZeneca to African nations. But even though the decision was not linked to concerns over blood clotting, experts said it could still magnify misinformation about the vaccine. And the African Union is shifting its focus to the Johnson & Johnson vaccine, which could add to the problem. Its use has been paused in the United States.
- On April 13, 2021, U.S. health agencies called for an immediate pause in the use of Johnson & Johnson’s single-dose Covid-19 vaccine after six recipients in the United States developed a rare disorder involving blood clots within one to three weeks of vaccination.
- All 50 states, Washington, D.C. and Puerto Rico temporarily halted or recommended providers pause the use of the vaccine. The U.S. military, federally run vaccination sites and a host of private companies, including CVS, Walgreens, Rite Aid, Walmart and Publix, also paused the injections.
- Fewer than one in a million Johnson & Johnson vaccinations are now under investigation. If there is indeed a risk of blood clots from the vaccine — which has yet to be determined — that risk is extremely low. The risk of getting Covid-19 in the United States is far higher.
- The pause could complicate the nation’s vaccination efforts at a time when many states are confronting a surge in new cases and seeking to address vaccine hesitancy.
- Johnson & Johnson has also decided to delay the rollout of its vaccine in Europe amid concerns over rare blood clots, dealing another blow to Europe’s inoculation push. South Africa, devastated by a more contagious virus variant that emerged there, suspended use of the vaccine as well. Australia announced it would not purchase any doses.
In African countries, public confusion over whether to get inoculated, and if so when and where to do so, has contributed to the expiration of doses. Like Malawi, South Sudan saw 59,000 unused doses expire this month.
The problem is not unique to African countries. Tens of thousands of jabs have also been thrown away in countries like France and the United States. But African countries face far more serious supply shortages. According to a New York Times database, Africa has the slowest vaccination rate of any continent, with many countries yet to start mass vaccination campaigns.
Countries like Ghana, which was the first African nation to receive doses from Covax, is about to run out of its initial supplies with no sense of when the next batch may come.
“This inequality negatively affects the entire world,” said Dr. Ngozi Erondu, an infectious disease specialist and a senior health scholar at the O’Neill Institute at Georgetown University. If “entire regions and countries remain insufficiently vaccinated,” she said, “it will continue to ravage populations with persistent morbidity and leave the larger global health community always vulnerable to the virus.”
