Pfizer boss says third Covid-19 jab 'likely needed' within 12 months

Pfizer recently announced that the vaccine was still highly effective up to six months after the second dose, and as time passes, they will continue to monitor how long protection from the virus lasts. It comes at a time when Americans are questioning the longevity both the Moderna and Pfizer vaccines offer patients with immunity against the virus.

Despite being vaccinated, health experts have also stated that individuals could still become infected with coronavirus since Pfizer and Moderna vaccines are not 100% effective.

Many believe this is also the case with COVID-19.

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

Bourla added that the EU's rollout - which has faced criticism for lagging behind countries like the United Kingdom and the United States - shouldn't be compared to quicker vaccination campaigns, saying that "the grass always looks greener in your neighbor's garden".

"In poorer countries, including in Africa, we sell it at cost".

The Pfizer vaccine, developed by the US-based company in partnership with German firm BioNTech, now plays a leading role in American and European vaccination campaigns.

Albert Bourla, Chief Executive Officer of Pfizer pharmaceutical, warned that a third vaccine dose might be necessary in comments published on Thursday.

But it's small beer compared to Kerry's effort to get China to change the year its emissions will peak from 2030 to 2025. The leaders of the three countries exchanged in-depth views on cooperation on addressing various issues at the summit.


Since the start of the pandemic, some researchers have speculated that in years to come, the world may deal with COVID-19 by repeating shots every year or so.

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.

"The current thinking is those who are more vulnerable will have to go first", he said.

"We don't know everything at this moment", he told the House Coronavirus Crisis Subcommittee. "So I think for planning purposes, planning purposes only, I think we should expect that we may have to boost".

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.

The agency said 129,494,179 people had received at least one dose while 82,471,151 people are fully vaccinated as of Saturday.

Walensky said some of these infections have occurred because the vaccinated person did not mount a strong immune response. SARS-CoV-2 seems to be mutating much slower than the flu, but several concerning variants have already emerged - which is why it's so important to generate immunity in as many people as possible.
