COVID Vaccine Boosters

|


There are news reports about the need for Covid boosters shot for those who have already bee vaccinated. According to CNN, the US Food and Drug Administration (FDA) is in internal discussions about laying out a strategy on Covid-19 vaccine booster shots by September.

A Biden administration official reportedly told CNN that their strategy would apply for all vaccinated people and a decision for those who are immunocompromised and face greater risk from the virus is expected sooner.

The agencies are engaged in a science-based, rigorous process to consider whether or when a booster might be necessary.

Dr. Anthony Fauci, the head of the National Institutes for Allergies and Infectious Diseases (NIAID), reportedly said that people with compromised immune systems may need additional protection after receiving a Covid-19 vaccine, and there is an effort to make vaccine boosters available to that population “very soon.”

We are trying very hard to get the regulatory mechanism in place very soon to get those individuals a boost that might bring up their immunity to the level where it should be, if possible.

In the Journal Nature, Ewen Collaway writes “the case for COVID-19 vaccine boosters at this point is weak. They might not be necessary for most people, and could divert much-needed doses away from others“.

Concerns over waning immunity and SARS-CoV-2 variants have convinced some countries to deploy extra vaccine doses — but it’s not clear to scientists whether most people need them.

“Wasting resources on boosters for those who are already protected against severe disease does not really make too much sense. Down the line, probably, we would need to think of it. But really, we don’t have strong arguments for it right now.”

According to media reports, both Moderna and Pfizer have said the Delta variants will lead to more breakthrough infections and that boosters may be needed before winter.

The journal Nature writes that “the data on whether and when boosters might be needed are trickling in. But it’s likely that key gaps will remain for some time”.

“It’s a difficult call and it will almost certainly have to be made on incomplete evidence,” Robert Aldridge, an infectious-disease epidemiologist at University College London, told journal Nature.

Coronavirus-19 vaccination watch

According to the US Centers for Disease Control and Prevention (CDC) COVID vaccination tracker page (as of August 7, 9 a.m.) 407,550,175 doses have been distributed and 350,627,188 doses administered. According MDH COVID-19 Response vaccine data (as of August 4) a total of 5,953,483 doses of Covid-19 (Pfizer & Moderna) vaccines have been administered in Minnesota. According to the MDH latest tally (as of August 6) the confirmed COVID-19 cases in Minnesota are 617,788 (out of 10,771,700 tested) with 7,694 deaths.
