Could we need a yearly COVID-19 vaccine like the flu shot?

Could we need a yearly COVID-19 vaccine like the flu shot?

Moderna also reported that its vaccine was also more than 90% effective against COVID-19 up to six months after the second dose, according to a review of its clinical trial data.

"Based on these data, the JCVI advises that it is preferable for pregnant women in the United Kingdom to be offered the Pfizer-BioNTech or Moderna vaccines where available", it said. "We will be having our vaccinations and we will be living our full lives".

Bulgarian Prime Minister Boyko Borissov explained earlier this week that the Pfizer vaccine's price was rising as sales were being negotiated, costing as much as 19.50 euros, up from 12 euros.

The prices are in sharp contrast to those of the rival shot produced by British-Swedish drugmaker AstraZeneca.

"So even if we need a booster in six months to a year this time around, it doesn't mean we can't get a better vaccine that could last two, three, four years." he said.

"In middle-income countries, we sell it for half the price", he said.

In February, Pfizer-BioNTech began studying a third dose of its existing vaccine among people enrolled in the early phase of the vaccine; the company's scientists are also developing a new version of the vaccine directed specifically against the aforementioned B.1.351 variant.

A total of 7,777,177 vaccine doses have been administered in long-term care facilities, the agency said.


While time will tell if additional doses are needed and how regularly, such boosters might not be needed as often as the annual flu shot, said Joseph Eisenberg, a University of MI expert in global diseases. So, when will you need your booster shot?

Among the most vulnerable population - residents 65 years and older - more than 70% have gotten a first dose, and more than 61% are fully vaccinated.

"We don't know everything at this moment", he told the House Coronavirus Crisis Subcommittee.

"We are studying the durability of the antibody response", he said.

"It seems strong but there is some waning of that and no doubt the variants challenge" that, he said.

He continued: "If you see the data for Europe, I think it's not behind other major complex countries".

Of 77 million people vaccinated in the United States, there have been 5,800 such breakthrough infections, Walensky said, including 396 people who required hospitalization and 74 who died. But the concern is that in some cases, they are occurring in people infected by more contagious virus variants. And after receiving a third shot, people should expect re-vaccination every year, he said.
