(Reuters) -Pfizer Inc said on Monday its COVID-19 vaccine provided strong long-term protection against the virus in a late-stage study conducted among adolescents aged 12 to 15 years.

A two-dose series of the vaccine was 100% effective against COVID-19, measured seven days through over four months after the second dose, the company said.

The long-term data will support planned submissions for full-regulatory approval of the vaccine in the age group in the United States and worldwide.

Pfizer (NYSE:PFE) and BioNTech will seek clearance for a 30 micrograms dose of the vaccine for those aged 12 and above.

The vaccine was authorized for emergency use in people aged 12-15 years by the U.S. Food & Drug Administration in May, and granted full approval for use in people aged 16 and above in August.

One way to reduce the governments payroll, is to give them a vaccine that, according to a recent European study, pretty much ruins the human DNA's ability to repair itself. Modern cleansing?

They said the same thing for adults but now preach for 3rd dose because efficacy wanes after a few months. So is that what "long term" means now? Six months? lol what a joke

If Pfizer is protected from lawsuits by the US government, it can say whatever it wants to say about its product, and Reuters, as usual, will gladly publish as fact anything Pfizer wants them to publish - no investigation necessary!
