“If you really want to study it to see that – how long it will take, how many people you have to put in the study – by then we’ll be in the arena already to have enough,” to have enough vaccine to circulate anyway. So from a theoretical point of view it would be good to know, if you give just one dose, how long is the durability and what the level of effect is, “Fauci said in” Meet the Press “.
“But what we have right now and what we need to go with is the science that we’ve been building up, and it’s really, really solid. We know that with each of them it’s either 21 days or 28 days. You can do both. You can get as many people in their first dose at the same time as you can within reason meet the second dose schedule. So it would be great to have the study, but I don’t think we could do it on time.
In terms of manufacturing, Fauci stressed that the doses “get off the line as quickly as possible”. He specifically cited an increase in the doses of Moderna and Pfizer available in March and April, as well as the single-dose Johnson & Johnson vaccine which is expected to be available in the coming months.
Former FDA commissioner Scott Gottlieb also commented on the availability of current Covid-19 vaccines, as well as their effectiveness, especially with regard to new emerging variants of the virus.
“We can assume that the new vaccines will probably be around 20% less effective against these new variants from Brazil and South Africa,” Gottlieb said on CBS’s “Face the Nation”.
But Gottlieb noted that while the protection against the newer variants is not as “deep” with the current vaccines, “you still get very good protection with these vaccines.”
When asked if the Biden administration’s distribution plan, based on dosing based on population, was still the best method, Gottlieb said, “I think at the moment [it is.]”
“We had a few days where 2 million vaccines were issued,” he said. “I think we’ll see this more consistently. That will be the execution rate. By the end of March, we will have delivered 250 million vaccines to the market, if the J&J vaccine is cleared. By April, we will probably be delivering 100 million. more vaccines on the market. “
