COVID-19 Vaccine Side Effects
This is the first in a series of explainers on vaccine
development and dissemination. In whose Vaccines Explained series, learn more
about vaccines, from how they function to how they're created to ensuring
safety and fair access.
COVID-19 vaccines are safe, and getting one will help you
from acquiring severe COVID-19 disease and dying from it. After getting
vaccinated, you may feel some minor side effects, which are indicators that
your body is preparing to defend it.
Why is it acceptable for vaccines to cause minor side
Vaccines are meant to protect you from disease without
putting you at risk of contracting it. When getting immunizations, it's usual
to have some mild to moderate adverse effects. This is because your immune
system tells your body to do specific things, such as boost blood flow to allow
more immune cells to circulate and raise your body temperature to kill the
Mild to moderate side effects, such as a low-grade temperature or muscle aches, are common and not to be concerned about: these are indicators that the body's immune system is reacting to the vaccination, specifically the antigen (a molecule that induces an immunological response), and is preparing to combat the virus. After a few days, these adverse effects normally subside.
Side effects that are common, mild, or moderate are
beneficial since they demonstrate that the vaccine is effective. It is not true
that the vaccine is useless if no adverse effects occur. It means that everyone
has a different reaction to the same situation.
vaccinations' most common adverse effects
COVID-19 vaccinations, like any other vaccine, can have side
effects, the majority of which are minor to moderate and go away on their own
within a few days. More serious or long-term side effects are conceivable, as
evidenced by clinical study findings. Vaccines are constantly checked for side
COVID-19 vaccination side effects have typically been mild
to moderate and have lasted only a few days. Soreness at the injection site,
fever, weariness, headache, muscle pain, chills, and diarrhea are common
adverse effects. The likelihood of any of these side effects happening after
immunization varies depending on the vaccine.
COVID-19 immunizations only protect against the SARS-CoV-2
virus, thus it's still crucial to stay healthy.
effects that are less common
A person should be asked to stay at the immunization site
for 15–30 minutes after getting the vaccine so that health workers are present
in case of any immediate responses. Individuals should notify their local
health professionals if they have any unexpected consequences or other health
problems following immunization, such as side effects that linger longer than
three days. Severe allergic reactions such as anaphylaxis have been recorded as
a less common side effect of some COVID-19 vaccinations; however, this reaction
is extremely rare.
National authorities and international organizations,
notably the World Health Organization, are keeping a close eye on any
unforeseen side effects from the COVID-19 vaccination.
The majority of side effects occur within the first few days
after receiving a vaccine. Hundreds of millions of vaccine doses have been
distributed since the first mass vaccination program began in early December
Concerns have been raised concerning COVID-19 immunizations
making people sick. However, none of the licensed vaccines contain the live
virus that causes COVID-19, thus COVID-19 immunizations cannot get you sick.
It normally takes a few weeks for the body to develop
immunity to SARS-CoV-2, the virus that causes COVID-19, after vaccination. So a
person could be infected with SARS-CoV-2 before or after immunization and still
get sick with COVID-19. This is due to the fact that the vaccine has not yet
had sufficient time to provide protection.
If you have side effects after getting vaccinated, it
signifies the vaccination is working and your immune system is reacting
normally. Vaccines are safe, and they can help prevent you from COVID-19.
