COVAX to purchase 40 mln doses of Pfizer-BioNTech vaccine

AFPThe Covid-19 vaccines so far require two shots given a few weeks apart

The delivery slowdown of COVID-19 vaccine doses from Pfizer-BioNTech is going to be far worse than the companies first warned Canada last week.

New CDC data released Friday shows that just 10 people who've gotten Moderna's vaccine in the U.S. have had severe (anaphylactic) allergic reactions, among more than 4 million shots delivered. 213,567 Kentucky residents have received their first dose of the vaccine.

"It is already meeting for another vaccine quite soon", Simao said.

The CDC urged locations administering Covid-19 vaccines to adhere to CDC guidance, including screening recipients for contraindications and precautions, having necessary supplies and staff members available to manage anaphylaxis, implementing recommended post-vaccination observation periods, and immediately treating suspected anaphylaxis with intramuscular epinephrine injection.

The CDC data documented the 10 cases of anaphylactic shock among a reported 4,041,396 first doses administered between December 21 and January 10.

Not only the United States but also countries like India, Israel and Norway reported cases of unexpected deaths of some vaccine receivers.

The Oregon Health Authority said on Wednesday that it will not delay administering the Moderna vaccine after their counterparts in California opted to pause distribution of a batch of the same vaccine over allergy concerns. Both doses of the series should be completed with the same product.

If people do happen to get a different vaccine for their second shot by accident, Bar-Zeev said it is likely "to work fine and likely to be well tolerated", but evidence is needed to be sure. -BioNTech SE vaccine released earlier this month found about 11.1 cases of anaphylaxis per one million doses administered, similar but somewhat higher than Moderna's 2.5 cases per one million doses.

The J&J vaccine doesn't have the same need to be kept super-cold, Fauci said, and only requires one dose.

Not to be out shadowed, drug maker Moderna has also created a vaccine that has proved efficient and has since been authorized and distributed for public administration. For more information about the vaccine, you can visit the CDC's website. Learn about antibodies. Learn how to evade them'.
