Hello and
welcome to Healthy Advice. I wouldn’t be wrong if I say that the year 2020
will be remembered as the “Covid Year” in history and we as a generation
watched this story unfold from the wet markets of Wuhan, china to every street
of every city in every country of this world. It has been more than one year of
this pandemic which has had a devastating effect on this whole planet. With
more than 92 million cases & 2 million deaths, this pandemic doesn’t seem
to stop. The virus is surging in many regions and countries that had apparent
success in suppressing the initial outbreaks and are also seeing a rise in
infections again.
The World Health
Organization has warned that the virus will continue to spread rapidly in the
coming months. Many European countries witnessed an increase in cases during
the autumn, and many countries implemented lockdowns and other restrictions to
curb the infections. United Kingdom is also experiencing another steep rise in cases
driven by a new, more easily spread, mutated variant of the virus. Several
coronavirus vaccines have now been approved for use, either by individual
countries, or the EU and WHO. There are currently more than 50 COVID-19 vaccine
candidates in trials.
Currently, Some vaccines
are authorized and recommended for COVID-19
Two vaccines that have been granted emergency use authorization by the
Central Drugs Standard Control Organization (CDSCO) in India are
Covishield®
(AstraZeneca's vaccine manufactured by Serum Institute of India)
And
Covaxin®
(manufactured by Bharat Biotech Limited).
COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19, without
us having to get the illness. Different types of vaccines work in different
ways to offer protection, but with all types of vaccines, the body is left with
a supply of “memory” T-lymphocytes, B-lymphocytes and antibodies that will
remember how to fight that virus in the future. It typically takes a few weeks
for the body to produce T-lymphocytes and B-lymphocytes after vaccination.
Sometimes after
vaccination, the process of building immunity can cause symptoms, such as
fever, muscle pain, fatigue etc. These symptoms are normal and are a sign that
the body is building immunity. So, it’s very important that you understand the
minor side-effects of Covid vaccine and also we will discuss some of the rare
but serious complications that can occur. Also we will talk about whether you
can get covid-19 from a covid vaccine? So, without further ado let’s begin.
The most common
side effects that you can experience after COVID-19 Vaccine include:
These are known
as minor or expected side effects of a vaccine and they can occur not just
after Covid vaccine but in fact after most of the vaccines that you receive.
These side effects occur because your body is adapting to the vaccine. You see,
Vaccines work by introducing a small number of bacteria, virus or toxin into
the body. Because the bacteria, virus or toxin have been killed or weakened,
there's no risk of contracting the disease in question. However, your body
responds as if it were under attack, and mounts an immune response. If, in the future,
you do encounter that disease, you'll have an army of cells and antibodies
ready to fight it. This means that any adverse effects you experience are
unlikely to be caused by the bacteria, virus or toxin. Most of the common side
effects such as a sore arm, redness and fever are caused by the injection, or
by your own immune system fighting against the weakened invaders.
What are the chances of serious side effects ?
Serious adverse
events, while possible, are very rare. Let’s take the example of yellow fever
that is also caused by a virus. According to the WHO, serious side effects occur
at a rate of around 0.09 to 0.4 cases per 10,000 doses of the yellow fever
vaccine, in populations who haven't been exposed to the virus. By contrast, the
serious form of yellow fever is fatal around half the time.
On a similar
note, the rate of serious allergic reactions is around 1-2 cases per million across
all vaccines. Compare that with the death rate for measles (around 1 in 500), and
for flu which causes around 200 deaths in the UK alone, every winter, and it's
obvious which is riskier.
What we need to
understand are the risks and benefits –
How many people
are dying from yellow fever; how many people are dying from measles VS how many died from any serious
adverse effect of the vaccine. Clearly, adverse effects are tragic for the individual
and the family but they are rare, and we need to balance this with the risks associated
with that disease. So, there is a remote chance that Covid-19 Vaccine can cause
a severe allergic reaction. A severe allergic reaction would usually occur within
a few minutes to one hour after getting a dose of the COVID-19 Vaccine. For
this reason, your vaccination provider may ask you to stay at the place where
you received your vaccine for monitoring after vaccination.
The simple
answer to this question is a “BIG NO”. None of the COVID-19 Vaccines contain SARS-CoV-2 virus, so it is not possible that you can CONTRACT covid-19 from the covid
vaccine.
So I hope I was
able to answer most of your questions regarding side effects of covid vaccine
in this blog . If you have any more queries make sure to write them down in the
