The coronavirus is spreading its wing rapidly around the world, especially in India.
Many countries have developed vaccines to control the pandemic. All countries around the world are running mass vaccination drives to get everyone vaccinated and to reduce the risk of infection.
There are currently no rules for taking two different vaccines worldwide. The World Health Organization and the US Centre for Disease Control (CDC) have recommended only two doses of the same vaccine.
The Medical Research Council of India (ICMR) also recommends taking both doses of the same vaccine. Different vaccine doses are in the experimental stages only.
However, due to the lack of adequate vaccines, things are not going as planned. The pressure is mounting on the companies to ramp up the production process.
Meanwhile, people are apprehensive and are mixing up their vaccines, those who took covaxin for their first dose are taking covishield for the second dose and vice versa.
In this context, scientists have conducted experiments to determine whether two different doses of vaccines can be effective, what would be the side effects?
The outcome of the research has shown that mixing up vaccines outweighs the benefits. Although there is no serious risk of taking two different doses of vaccine, experts point out that it is best not to take two different doses of the vaccine taking into account the circumstances.

A recent report published in The Lancet Journal found that those who took two doses of different vaccines had side effects.
These may be more or less the same as the side effects of taking the first dose. It also revealed that these depend on the symptoms that appear when the two vaccines are combined.
Dr. Matthew Snape, an associate professor of pediatrics and vaccinology at the University of Oxford and chief investigator on the trial said that “such side effects are commonly observed but, in this case, it is very frequent but that they would soon subside.
The University of Oxford is experimenting with the outcome of taking two different vaccines in two doses. As part of this, the available vaccines are tested by mixing the doses.
830 volunteers were given different doses over a period of 28 days. The experiments were initially performed on the AstraZeneca and Pfizer vaccines.
The two vaccines were given in four combinations. 34 percent of People who took AstraZeneca first Dose, and Pfizer’s second dose reported symptoms such as high fever, headache, and fatigue.
Pfizer’s first dose and AstraZeneca’s second dose showed 41 percent of adverse effects.
Side effects were seen in only 10% of people who took two doses of AstraZeneca and 21 percent with those who took Pfizer’s doses.
However, the researchers said that these were not as serious as in hospitals. And the researchers believe that more extensive studies need to be conducted.
Although, national and international experts say that different vaccines combination should not be taken under any circumstances. The Indian Ministry of Health has clarified that people who have taken the first dose of the vaccine must take the same vaccine if they have to take the second dose in other states/districts.
