A study in England found that the ‘mix-and-match’ approach to covid-19 vaccines, ie, the use of different brands of vaccines for the first and second doses, provides better protection against coronavirus.
The ‘Com-Cove Experiment’ examined the effects of using two doses of Pfizer, two doses of AstraZeneca or one of them. The BBC cited the study on Monday, saying all the blends have done well in strengthening immunity. The report cited experts as saying the study provides an alternative opportunity for the vaccine.
England’s Deputy Chief Medical Officer Jonathan Van-Tom said a similar dosage was successful in the country at the time and did not require a replacement. However, the vaccine produced after this blend has yielded good results for survival.
He says that in the future it remains to be seen whether ‘mixed dose can provide us with even more optimization for the booster program’. It is known that two doses are currently being vaccinated to produce antibodies in the body and destroy the corona virus.
