NIH Begins Testing Mixed COVID-19 Vaccine Schedules

NIH Begins Testing Mixed COVID-19 Vaccine Schedules

The U.S. National Institutes of Health (NIH) has announced that it has begun an early stage Phase 1/2 clinical trial to examining what happens when an adult who is fully vaccinated with one type of COVID-19 vaccine, is given a different booster vaccine from another manufacturer three to four months later.1

Currently, there are three COVID-19 vaccines being distributed under the U.S. Food and Drug Administration’s (FDA) emergency use authorization (EUA) status: Pfizer/BioNTech COVID-19 vaccine, Moderna COVID-19 vaccine and Janssen COVID-19 vaccine.2 The COVID vaccines manufactured by Pfizer/BioNTech and Moderna’s COVID-19 currently require two doses given three to four weeks apart, while Janssen vaccine requires one dose.3

Vaccine Makers and Scientists Say People Will Need Booster COVID-19 Vaccines

The clinical trial comes after vaccine manufacturers and public health officials have said that fully vaccinated people will eventually need a booster dose of COVID-19 vaccine because artificial vaccine acquired immunity will likely wane over time.4 5 Some have speculated that the COVID-19 vaccine may become an annually recommended vaccine similar to the annual influenza vaccination.6

Anthony Fauci, MD, director of the National Institutes of Allergy and Infectious Diseases (NIAID) said:

Although the vaccines currently authorized by the U.S. Food and Drug Administration offer strong protection against COVID-19, we need to prepare for the possibility of needing booster shots to counter waning immunity and to keep pace with an evolving virus.7

150 Volunteers Enrolled in the Clinical Trial

The purpose of the clinical trial is to examine the immune responses of administering a different COVID-19 booster vaccine than the one originally administered to trial participants.8 Dr. Fauci added…

The results of this trial are intended to inform public health policy decisions on the potential use of mixed vaccine schedules should booster doses be indicated.9

Currently, there are 150 volunteers registered in the clinical trial, who have received either one of the three EUA COVID-19 vaccines. Each vaccine group will have enrolled some 25 people between the ages of 18 and 55 and about 25 people in the 56 years and older age group.10

The participants will receive a single booster dose of the Moderna vaccine twelve to twenty weeks following vaccination. They will be monitored for a period of one year after the administration of the booster vaccine to evaluate immune responses against current and emerging variants of the SARS-CoV-2 virus.11

People who have not yet received an EUA COVID-19 vaccine are also eligible to enroll in the trial in a separate cohort. These participants will receive the two-dose Moderna COVID-19 vaccine and will be assigned to receive a booster dose of a vaccine about 12 to 20 weeks later. NIH officials said initial findings should be available at the end of summer 2021.12

Canada Recommends “Mixing and Matching” COVID-19 Vaccines

Canada’s National Advisory Committee on Immunization (NACI) updated its guidance recommending the mixing and matching of second doses of COVID-19 vaccines. NACI is now advising Canadians to combine either the AstraZeneca/Oxford University, Pfizer/BioNTech or Moderna/NIAID vaccines interchangeably.13

For Canadians who have had a first dose of Pfizer/BioNTech or Moderna COVID-19 vaccine, NACI recommends they can now take either of the two vaccines as a second dose because they both use mRNA technology.14 The recommendations also state that first dose of the AstraZeneca COVID-19 vaccine can be followed by a dose of either Pfizer/BioNTech or Moderna COVID-19 vaccines.15

The updated NACI recommendations state:

No data currently exist on the interchangeability of COVID-19 mRNA vaccines… At this time, there is no reason to believe that mRNA vaccine series completion with a different authorized mRNA vaccine product would result in any additional safety issues or deficiency in protection.16

Theresa Tam, MD, Canada’s Chief Public Health Officer said that, while there is no data to support the recommendations, there are “ongoing” studies to test the effectiveness of the approach that have yet to be published.17

She said:

This is not a new concept, so having a multi-dose series in terms of vaccines given by manufacturers is something that public health have used over time for many other vaccines. When vaccine programs and supplies change this is not an unusual thing to do.18

    What lunacy. We don’t even know the effects of having one set of injections and won’t for many years. These institutions are beyond insane.

    Boy, they really want to screw up people, with the ultimate goal of killing anyone stupid enough to start doing this in the first place. At least when these vaxxtards start dying off, the Intelligence Quotient should go up, right?

    It makes sense for a criminal poisoning enterprise (virology-vaccinology, CDC, Pharma, etc) to encourage mixing of the poisons…

    This is Toxic Substance Profiteering 101: make sure if you are going to try to profit from widespread poisoning of people that you subject them to a whole bunch of different toxic poisons at the same time so that they will find it very difficult to prove which substance specifically caused which of their problems (when in reality the combinations will be even more toxic).

    Was it the Roundup, Atrazine, or any of 100 different poisons in your GMO ‘food’? Or the toxic Pharma drugs? Was it the MMR vaccine? Was it the Covid vaccine? Was it the JJ Covid vaccine or the Moderna Covid vaccine or the 23rd booster of the Covid vaccine? Or some or all of them?

    The only survival strategy in this toxic hell humans are creating is to opt out of the poisoning ‘marketplace’ and avoid all these poisons as best you can… Give your body good clean nutrition and it can keep you well.

    Hey NVIC, thank you for showing a photo of the NIH logo. I had no idea (though I am not surprised) that their logo has the pyramid on it. If you know anything about occult/satanic symbols, you will recognize their ‘secret signs’ to each other and where their fealty lies. Seeing as the NIH is in with the other evil people like Bill Gates who wants to destroy almost all of humanity, it shows the link to these people who want to only destroy. I mean, name ONE disease that all these ‘researchers” with their billions upon billions of dollars has CURED just by some new drug or vaccine! Answer: ZERO.

    I can only imagine what will really happen when they start experimenting further on dupes and trusting fools that haven’t died (yet) of the dangerous biologicals under the label “vaccine”.

    I’d also be curious to see if the birth rate plummets after the majority of the rubes have gotten these abominable shots.

    June 10, 2021 Think Twice Before Giving the COVID Vax to Healthy Kids/ Med Page Today

    Given that the risk of a healthy child dying is between zero and infinitesimally rare, it’s understandable that many parents are appropriately asking, why vaccinate healthy kids at all?

    June 21, 2021 Majority of US Physicians Decline COVID Shots, According to Survey By Association of American Physicians and Surgeon

    The AAPS survey also showed that 54 percent of physician respondents were aware of patients suffering a “significant adverse reaction.” Of the unvaccinated physicians, 80 percent said “I believe risk of shots exceeds risk of disease,” and 30% said “I already had COVID.”
