Moderna said a booster dose of its COVID-19 vaccine should provide protection against Omicron.
Moderna announced the preliminary laboratory data in a press release.
Both Moderna and Pfizer are developing shots to better match Omicron when needed.
Pharma major Moderna said a booster dose of its COVID-19 vaccine should provide protection against the fast-spreading Omicron variant. The company said laboratory tests showed that the half-dose booster shot increased levels of so-called neutralizing antibodies capable of fighting Omicron by 37 times.
And a full-dose booster was even stronger, causing an 83-fold jump in antibody levels, albeit with an increase in common side effects, whereas for most Moderna boosters using half-dose shots, a full-dose The third shot has been recommended for people with weakened immune systems, Moderna said.
Moderna announced the preliminary laboratory data in a press release and has yet to be scientifically reviewed. But a trial by the US National Institutes of Health announced last week by Dr. Anthony Fauci found a similar leap.
Similarly, Pfizer’s trial found that its COVID-19 vaccine produced an equally big jump in micron-fighting antibodies. Vaccines made by Pfizer and Moderna, both made from mRNA technology, are used by many countries around the world to fight the coronavirus.
Together, the available evidence supports a growing number of health officials’ arguments that people can get their boosters as soon as they are eligible.
Antibody levels predict how well a vaccine can prevent infection with the coronavirus but they are just one layer of the immune system’s defenses.
Other research suggests that even if people do experience a successful infection, the vaccine should still provide good protection against serious illness.
Both Moderna and Pfizer are developing shots to better match the Omicron variant when needed.
The Omicron version, which is probably more contagious than the Delta version, was detected in at least 47 US states as of Sunday, as the first case in the country was detected in California on December 1.
