Srinagar , July 09: Doctors Association Kashmir (DAK) on Friday said mixing of different Covid-19 vaccines provides better protection against the virus.“Combining different vaccines generates a stronger immune response,” said DAK President and influenza expert Dr Nisar ul Hassan.“According to Oxford-led Com-Cov study, giving people first and second doses of different vaccines leads to a more robust immune response than two doses of a single vaccine,” he said.“The study found that one dose of AstraZeneca followed by second dose of Pfizer generated a stronger antibody response than those who got two doses of AstraZeneca.” Dr Nissar in a statement to CNS said, another study conducted by the Carlos 111 Health Institute in Spain found that the first dose of Astrazeneca followed by second dose of Pfizer was entirely safe and effective in controlling the spread and prevention of the disease.“Combining vaccines is called heterologous prime-boost and it trains the body’s immune system to recognize the virus in more than one way,” he said.“This mix-and-match strategy has been deployed for vaccines against other diseases, such as Ebola.
