Vaccine 2nd doses issue: US says necessary, Canada and Germany extend

Thu, 2021-03-04 11:05 — mike kraft

Two doses of Pfizer and Moderna's Covid-19 vaccine are necessary, officials say, but questions still linger The United States is holding firm to the strategy to administer two doses of the Moderna and Pfizer/BioNTech Covid-19 vaccines a few weeks apart. Still, the idea of expanding the supply by dispensing only one dose hasn't faded away. The Trump administration's surgeon general, Dr. Jerome Adams, said in a tweet on Tuesday that the good protection available with one shot "is better than great protection for a few."

B.1.1.7, first identified in Britain, has demonstrated the power to spread far and fast. In South Africa, a mutant called B.1.351 can dodge human antibodies, blunting the effectiveness of some vaccines.

MOSCOW (Reuters) - A Russian trial testing the effectiveness of revaccination with the Sputnik V shot to protect against new mutations of the coronavirus is producing strong results, researchers said on Saturday.

“(A) recent study carried out by the Gamaleya Centre in Russia showed that revaccination with Sputnik V vaccine is working very well against new coronavirus mutations, including the UK and South African strains of coronavirus,” said Denis Logunov, a deputy director of the centre, which developed the Sputnik V shot.

Results of the trial are expected to be published soon, but this was the first indication of how the tests are going. No further details were available yet.

So-called viral vector shots - such as Sputnik V and a shot developed by AstraZeneca - use harmless modified viruses as vehicles, or vectors, to carry genetic information that helps the body build immunity against future infections. ...
