GENEVA (Reuters) - The World Health Organization's chief scientist has advised individuals against mixing and matching COVID-19 vaccines from different manufacturers, saying such decisions should be left to public health authorities.

"It's a little bit of a dangerous trend here," Soumya Swaminathan told an online briefing on Monday after a question about booster shots. "It will be a chaotic situation in countries if citizens start deciding when and who will be taking a second, a third and a fourth dose."

Swaminathan had called mixing a "data-free zone" but later clarified her remarks in an overnight tweet.

"Individuals should not decide for themselves, public health agencies can, based on available data," she said in the tweet. "Data from mix and match studies of different vaccines are awaited - immunogenicity and safety both need to be evaluated."

The WHO's Strategic Advisory Group of Experts on vaccines said in June the Pfizer Inc (NYSE:PFE) vaccine could be used as a second dose after an initial dose of AstraZeneca (NASDAQ:AZN), if the latter is not available.

A clinical trial led by the University of Oxford in the UK is ongoing to investigate mixing the regimen of AstraZeneca and Pfizer vaccines. The trial was recently expanded to include the Moderna (NASDAQ:MRNA) Inc and Novavax Inc vaccines.

There are too many conspiracy theories that the people on here believe. I would rather believe a specialist than the people who post here that probably never even got their GED.

We are doomed. The scientists and govt are in a campaign to deliberately eliminate masses. Like or not.

You do realize if there were a conspiracy to “reduce the masses”, there are far better ways to do it than using CoVid - a virus with a relatively low mortality rate that can be neutralized with a simple vaccine???

I'll bet the best part of being a scientist is constantly having your hard work and research questioned by people who spent every science class peeling glue from their hands

The vaccines don't work, and no one fully knows their side effects. None are FDA approved yet, nor should they be. But like the WHO, the FDA is probably being taken over or influenced by political hacks so I would be surprised if they do ultimately reject these vaccines. I mean the SARS vaccine was pulled out of the market when just a few people past away because of it. These vaccines have buried thousands!

Academia is absolutely cutthroat and not cooperative or supportive at all.  As soon as you publish research, people will make it their purpose to disprove it.  That is just how science works - research can't be 'infallible'.  It has to be open to being proven wrong.  Unfortunately, a lot of 'research' being performed today is of very poor quality.  Though you don't mention the "best part of being a scientist" as being harassed, stalked, mocked, etc, for publishing treatments for early COVID cases so that people don't get to the hospital stage.

"It will be a chaotic situation in countries if citizens start deciding when and who will be taking a second, a third and a fourth dose." - Too late.

This [warning] illustrates the problem: why have the reports come in slightly weaker since the Great Liquidity Tsunami of 2021 began? Mixed-messaging. We are told to "live it up, everything is back to normal." Followed by "Careful, be sure to wear your mask and social distance!" This whole plan is DOOMED to failure.

LOL completely flip flopping again, these people have no clue what they are doing, for the past two weeks everywhere on MSM they were pushing the agenda of mixing vaccines. How do people believe anything these people/MSM are saying, the head of all of this - Fauci - is even responsible for supporting/funding the lab that created the virus. Just keep shifting the goal post as the narrative falls apart: "Masks and the vaccine is super effective and stops the spread and are super duper safe"...."okay masks do not really stop the spread by a lot, maybe two masks will work...also you can still get and transmit the virus even if you are vaccinated...oh and it only causes a little blood clots and heart inflammation"...etc etc...*next month* "okay maybe wear 7 masks and get a mixture of all the vaccines and you will have a 10% less change of getting a virus less deadly than the common flu...and they only cause a few strokes and a little cancer"

The whole vaccination campaign is data-free since 2 year clinicals were never done.
