An official from the Omani Ministry of Health spoke exclusively to Times of Oman, "A person receiving two doses of Pfizer vaccine may need a third dose 12 months after the date of the second dose, according to the studies and researches as stated by Pfizer". "We will be having our vaccinations and we will be living our full lives".

The head of Pfizer said Thursday the company's Covid vaccine, among the priciest on the market, is no more expensive than the cost of a meal and will not be sold to poor countries for a profit.

More than 12,000 vaccinated participants were the base for Pfizer's data. "Because the pool of people is what defines how many replications the virus will do and defines... how many variants will appear".

"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.

Pfizer CEO Albert Bourla has said he is confident that life in Europe will return to normal in the fall.

Biden speaks with Putin, suggests summit
Russian Federation in recent weeks has stepped up troop movements near its border with Ukraine. Biden said in a March interview that he agreed Putin is a "killer".

The Biden administration's COVID response chief science officer David Kessler said earlier on Thursday that Americans should expect to receive booster shots to protect against coronavirus variants.

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

Phase 3 trials carried out on 2,260 adolescents in the United States "demonstrated 100 percent efficacy and robust antibody responses", the companies said in a statement.

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

"So I think for planning purposes, planning purposes only, I think we should expect that we may have to boost". By the middle of April, around 120 million people in the US had received at least one dose, according to figures from the US Centers for Disease Control and Prevention.

In the United States, health officials are already preparing for booster doses to be issued between nine and twelve months after people are fully vaccinated.
