Pfizer's 4th COVID-19 vaccine shot data is now being prepared by the health firm. Once it is completed, it will pass the data to FDA (Food and Drug Administration) for approval.
A vial of the Pfizer/BioNTech Covid-19 vaccine is seen during a vaccination clinic at the Sir Ludwig Guttmann Health and Wellbeing Centre on December 15, 2020 in Stratford, England. After rolling out the vaccine to dozens of "hub" hospitals last week, the NHS is now enlisting several hundred primary care practices in its covid-19 vaccination campaign.
Right now, most vaccines only require three shots, which already includes the booster shot. But, it seems like the third one is not enough since Pfizer wants to implement the fourth one.
Pfizer CEO Albert Bourla said that improving the immune system further is essential since Omicron is still affecting many countries across the globe.
Pfizer 4th COVID-19 Vaccine Shot Data
According to NBC News' latest report, the required two shots of Pfizer vaccines are still efficient against the Omicron variant.
Sodium chloride is measured to be added to a phial of the Pfizer/BioNTech COVID-19 vaccine concentrate ready for administration at Guy's Hospital, in central London on December 8, 2020. - Britain on December 8 hailed a turning point in the fight against the coronavirus pandemic, as it begins the biggest vaccination programme in the country's history with a new Covid-19 jab.
With the third shot, the immune system can be enhanced. However, Bourla announced their latest discovery. He said that the current booster shot's effectiveness wanes against Omicron after three to four months.
Using this finding, he concluded that another booster shot is now needed to neutralize the new COVID-19 variant.
But, Pfizer's spokesperson, Kit Longley, said that the results they acquired are still in the early and preliminary stages.
"We will continue to collect and assess all available data and remain in open dialogue with regulators and health authorities to help inform a Covid-19 vaccine strategy as the virus evolves," added Longley.
New Pfizer Vaccine Also Being Developed
CNBC reported that Pfizer is also creating another vaccine that is claimed to be effective against Omicron and other existing COVID-19 variants.
However, Bourla explained that they are still cautious when it comes to developing new vaccines. He added that the world can't have new medicines against the novel coronavirus every five or six months.
In other news, a new study recently claimed that COVID-19 face masks have titanium dioxide particles that can cause cancer. Meanwhile, COVID-19 swab tests previously raised DNA privacy concerns.
