As the COVID-19 vaccines are steadily being spread worldwide, many more vaccine candidates are also being tested in clinical trials. Several more vaccines are expected to be approved for use in the coming months.

Although there are variations in vaccine effectiveness identified by scientists based on clinical trial results, all approved vaccines have undergone rigorous safety monitoring. COVID-19 vaccines, like many other vaccines, have a high rate of side effects. Still, people have many questions about these vaccines.

Are they safe? Do I need to get a Covid 19 test if I have symptoms after getting vaccinated? Let us answer the most asked questions for you before you look for “drive through testing sites”.

1. How Does a COVID-19 Vaccine Work in My Body?

Your immune system will learn to identify the coronavirus after receiving the COVID-19 vaccine. When you have the vaccine, the immune system produces antibodies (also known as “battle cells”) that reside in your blood to shield you from the infection if you become sick.

When a population lacks enough members to combat the coronavirus, it has nowhere to go. This means we’ll be able to halt the outbreak faster and come to a move closer to bringing an end to the pandemic.

2. What Kinds of Side Effects Are Common After Having the Vaccine?

As in most regular vaccinations, the most frequent side effects include a swollen shoulder, nausea, fever, and muscle pain.

These signs indicate that the vaccine is effective. These side effects were most common within two days of receiving the vaccine in the Pfizer and Moderna trials. They lasted about a day. After the second dosage, side effects were more frequent than after the first. The side effects of the Johnson & Johnson clinical trials lasted an average of one to two days.

People over 55 were less likely than younger people to show side effects from all three vaccines.

3. What Are the Components of Vaccines?

There are some rumours on social media about the ingredients, and they’re all urban legends. The COVID-19 vaccines contain components that are very common in vaccines.

They include the active ingredient, mRNA or modified adenovirus, and other ingredients such as fat, salts, and sugars that preserve the active ingredient. They aid in its function in the body and protect the vaccine during storage and transportation.

4. Is There a Connection Between The COVID-19 Vaccine & Infertility?

This is a fallacy spread by non-scientific media on the internet. There is no evidence to back up this argument. For further information on the vaccines, see the FDA’s COVID-19 Vaccines website. The FDA will disclose details about additional vaccines until they are approved.

5. If I Have an Allergic Reaction, Should I Get Vaccinated?

People with a history of severe allergic reactions, such as anaphylaxis, a previous dose of an mRNA or viral vector vaccine, or any component in the Pfizer-BioNTech, Moderna, or Johnson & Johnson–Janssen COVID-19 vaccines, must not get the vaccine.

To check for an adverse response, the Advisory Committee on Immunization Practices (ACIP) advises that clinicians watch all patients for at least 15 minutes after administering the vaccine.
