WHAT IS A VACCINE?
A vaccine is an agent which, when administered to our body,
stimulates our immune system to produce antibodies without us having to
become infected with the real disease.
HOW VACCINATION WORKS?
Vaccination works by tricking our body into believing it is
experiencing a full-scale assault by an infectious agent so that the
immune system can fortify its defenses. During vaccination, a harmless
version of a germ is introduced to the body and the immune system
responds by producing antibodies to attack the intruder. Thereafter,
memory of this encounter remains so whenever real infection enters the
body our immune system quickly recognizes and neutralizes it.
ARE VACCINATIONS SAFE?
Like any medicine, vaccines may cause side effects - but getting a
vaccine is far safer than getting the disease. The most common
reactions include pain, redness, and swelling in the area of the
injection or a low-grade fever. Usually Paracetamol, given as drops or
syrup will take care of these side effects.
Serious adverse reactions to vaccines are rare but exist. Reactions
will depend on the type of vaccine given, so ask your doctor about the
possible reactions. Also, if you've had reactions to vaccines in the
past, let your doctor know.
