AstraZeneca and Pfizer combination would be more effective against Covid19

Receiving one dose of AstraZeneca followed by one dose of Pfizer is believed to show better results than using two doses of AstraZeneca vaccine. Several recent studies have confirmed better immune system response after mixing Covid-19 vaccines.

An Oxford University study shows that mixing both vaccines, boosts immunity by 60%. Research conducted in Germany also confirms this result and assures that combining the jabs would not increase the side effects than when using only one type of vaccine.

Another study, from South Korea, shows a six-fold increase in antibody levels after using a combination of AstraZeneca and Pfizer.
