STUDY: AstraZeneca booster dose significantly neutralises Omicron

British pharmaceutical giant AstraZeneca has revealed that a third, or ‘booster’ dose of its COVID-19 vaccine significantly lifted antibody levels against the Omicron variant.

This is based on a recent laboratory study whose findings suggest that AstraZeneca’s vaccine and its preventative monoclonal antibody treatment, Evusheld, “retains neutralisation activity” against Omicron.

“The third dose booster vaccination neutralised the Omicron variant to levels that were broadly similar to those observed… after the second dose against the Delta variant,” AstraZeneca said in a statement.

According to the statement, the levels at which antibodies became neutralised from the booster jab were also higher in individuals who had previously been infected and recovered naturally.

Meanwhile, the study was conducted by investigators from the University of Oxford, which is the academic institution that helped AstraZeneca develop the vaccine last year.

Researchers also analysed blood samples taken from individuals infected with COVID-19 as well as those vaccinated with a booster and those who had reported the a previous COVID infection.

“It is very encouraging to see that current vaccines have the potential to protect against Omicron following a third dose booster. These results support the use of third dose boosters as part of national vaccine strategies, especially to limit the spread of variants of concern, including Omicron,” said University of Oxford professor John Bell, one of the researchers.

Pfizer to become the vaccine of choice for BVI

While AstraZeneca has revealed this finding, the Ministry of Health here in the BVI that announced Pfizer will become the vaccine of choice in the territory as it expects the supply ability of AstraZeneca to dwindle in the new year.

The Acting Chief Medical Officer (CMO) Dr Ronald Georges said Oxford University in the UK carried out a large trial to determine which vaccines would be most effective as boosters overall and the results showed mRNA vaccines such as Pfizer would be best.

Dr Georges also announced that persons who have completed their primary vaccination with the two-dose regimen like AstraZeneca can receive the Pfizer booster three months after completion of their last dose.

Earlier this month, the ministry received 4,680 doses of the Pfizer vaccine from the United Kingdom and more are expected to become available in January.

      Because all of us idiots were telling the minister we were not taking Astra because Phizer is better.

      Stop complaining and be happy we have access to world class and approved vaccines.

    Worldwide people are having booster shots. Usually different to the first two vaccination shots but not always. Pfizer and Moderna are being used as the best options

    Many people said they didn’t want to take AZ and wanted Pfizer so you now have Pfizer so as a booster or your first and second shot you got what you asked for

    Vaccines prevent hospitalization and death but they don’t stop you getting covid. We know that so it isn’t news that some vaccinated people caught covid

    The world can’t keep shutting down. We have to learn to live with covid. Getting boosted will help that. Protect lives and jobs and businesses and the BvI.

    Now is the time for action to protect us all.

      @ Sensible Head

      “Vaccines prevent hospitalization and death but they don’t stop you getting covid. We know that so it isn’t news that some vaccinated people caught covid”

      Vaccines do not prevent hospitalization and death. Stop with this misinformation. If you say that they decrease the chance of hospitalization maybe that is the case but however we have Boris the Clueless stating that 90% in intensive care are double vaccinated? Just because they want to sell the booster. If they are there after 2 shots what makes you think they won’t be there after 3? Would that not wane after time ?

      Even the boostered can be hospitalized. There is a study that shows the shot may wane after 10 weeks.

      Fact is that the majority now getting sick and hospitalized are vaccinated. Time to focus on early treatments and healthy lifestyle campaigns as the vaccines are failing.

    Pretty certain the whole you need a third one is a pile of crap. They just found out that whar ever it’s doing to us doesn’t work as well as it should so oh look here is another variation and whoops sorry about all the people dying from heart disease and autoimmune disorders that have increased massively since we all took the shots to save our lives but don’t actually.

  6. So says:

    If already have astra zeneca can we now take the pfisar
