What Can We Expect From The COVID Vaccine?

COVID-19 vaccinations are both safe and effective in saving lives as shown in studies. However, one needs to know exactly what to expect from a vaccine. This is because of the scarce information available to us about covid vaccines specifically. To get an idea of expectations from the various Covid-19 vaccinations, we first need to understand how it works.

Let us start with a basic understanding of how vaccines work.

Do you know how your body is fighting illness on its own? Whenever a germ, like a coronavirus, infiltrates your body, they tend to multiply. Our body, with the help of essential white blood cells, fights the infection off.

Once it has dealt with the infection, the body’s immune system remembers the invader and how to fight it off. When you contract the same infection again, your body will deal with it quicker than it did the first time.

So does the covid vaccine contain the virus or the germ itself? The answer is: no it does not.

Vaccines stimulate the infection and trigger your body’s built-in response system. This infection does not cause the illness but merely makes the body produce antibodies for the germ. The imitated infection can sometimes induce mild symptoms, like fever, after receiving a vaccination. Minor symptoms are common and should be expected while the body works on building immunity.

After combating the imitated infection, the body retains a memory of it and how to fight it in the future in different lymphocytes.

COVID-19 is caused by a coronavirus that features protein spikes on each viral particle. These spikes aid viral attachment to cells and disease transmission. Let us understand how does the vaccine helps boost the immune system.

The Covid vaccine is a kind of mRNA vaccine.

 “mRNA vaccines tell our cells how to make a protein (or simply a fragment of a protein) that triggers an immunological response in our bodies.” – WHO

The body is trained in recognizing these spike proteins and attack the coronavirus that contains them.

If a person is exposed to the coronavirus, a successful vaccination will protect them by decreasing their chances of contracting COVID-19. The vaccine’s effectiveness in preventing hospitalization and fatality is far more significant. All three vaccinations are now extremely effective in reducing these.

Protection and Immunity

There is presently insufficient data to say whether or not people are protected against contracting COVID-19 after developing natural immunity to it. Natural immunity to COVID-19 may not persist long as per the preliminary findings. To properly comprehend this, more research is required. Hence, vaccination will benefit those who have previously developed natural immunity to it.

When fully vaccinated, remember

Getting fully vaccinated does not mean you get to disregard the covid guidelines. A fully vaccinated person is also required to wear a mask and maintain social distancing as they did before.

Do vaccines protect against the Covid-19 variants?

More research is needed to determine how effective the existing COVID vaccinations are against the variations. According to a growing amount of evidence, most vaccinations elicit adequate immunity to maintain significant effectiveness against most variations, particularly in the cases of severe illness, hospitalization, and death. Variants have a greater influence on efficacy against mild illness and infection without disease than on more severe outcomes.

Vaccinations’ ability to provide long-term protection against disease is most likely due to the wide immune response they elicit, which implies that viral mutations or alterations are unlikely to render vaccines entirely useless. If any of these vaccinations lose their effectiveness against one or more variations, it will most likely be feasible to alter the vaccine’s composition to protect against these variants. However, it will require time and more data for a proper analysis. On new COVID-19 viral strains, data is still being collected and analyzed.

Expected Side-Effects

COVID-19 vaccinations might produce minor, short-term adverse effects including a low-grade fever or discomfort or redness at the injection site, just like any other vaccine. Most vaccination responses are minor and go away on their own after a few days. Vaccines can have more significant or long-lasting adverse effects, although these are exceedingly rare. Vaccines are continuously evaluated for as long as they are in use to discover uncommon side effects and develop strategies to prevent them.

The majority of COVID-19 vaccine side effects were mild to moderate and only lasted a few days. Fever, tiredness, headache, muscular discomfort, chills, diarrhea, and pain at the injection site are some of the symptoms that WHO claims are to be the likely side-effects. Depending on the COVID-19 vaccine, the chance of any of these side effects following vaccination varies.

Rest, lots of non-alcoholic drinks, and paracetamol/acetaminophen for the common side effects may usually be helpful. If the tenderness (pain) where the injection was given worsens after 24 hours, or if the side effects do not go away after a few days, you are advised to contact your healthcare practitioner.

If you experience trouble breathing, chest discomfort, disorientation, loss of speech, or movement, get medical help right away.

In this attempt to explain how the vaccine works on the virus and what to expect post-vaccination, we have tried to curate a comprehensive guide that is most likely to help. Remember, beware of what facts you trust, and always check your information. Stay safe.
