What to expect after vaccination - Effects of
Do I need to use the mask/other COVID-19 appropriate
precautions after receiving the vaccine?
Yes, it is absolutely necessary that everyone who has
received the COVID-19 vaccine should continue to follow the
COVID-19 appropriate behaviour i.e., mask, do gaj ki doori
and hand sanitization to protect themselves and those around
from spreading the infection.
2) How long I will remain protected after vaccination?
Longevity of the immune response in vaccinated individuals
is yet to be determined. Hence, continuing the use of masks,
handwashing, physical distancing and other COVID-19
appropriate behaviours is strongly recommended.
3) Does vaccination protect me against newer strains /
mutated virus of SARS-CoV 2?
The body responds to vaccination by making more than one
type of antibodies to virus parts including spike protein.
Therefore, all vaccines are expected to provide reasonable
amount of protection against the mutated virus also. Based
on the available data the mutations as reported are unlikely
to make the vaccine ineffective.
4) In how many days will the vaccination create an adequate
immune response and protection?
Adequate immune response takes 2-3 weeks after completion of
entire vaccination schedule i.e., after the second dose of
COVISHIELDŽ and COVAXINŽ.
5) Should you avoid alcohol after receiving the COVID-19
As per experts, there is no evidence of alcohol impairing
the effectiveness of the vaccine.
6) What precautions I need to take after receiving the
Both the vaccines are safe but in case of any discomfort or
complaint, ask the beneficiary to visit the nearest health
facility and/or call the health worker whose phone number is
given in the Co-WIN SMS received after vaccination.
7) Is it important for me to receive the same vaccine during
As the vaccines available are not interchangeable, it is
important to receive the second dose of same vaccine as the
first one. The Co-WIN portal is also going to help to ensure
that everyone receives the same vaccine.
8) Does this vaccine provide herd immunity?
When an increasing number of people get vaccinated in the
community, indirect protection through herd immunity
develops. The percentage of people who need to be immune in
order to achieve herd immunity varies with each disease. For
example, its 95% for measles, however the proportion of the
population that must be vaccinated against COVID-19 to begin
inducing herd immunity is not known.
