Michael Giannulis Discusses COVID-19 Vaccine and Possible Side-Effects

Now that the COVID-19 vaccines, approved and given out to front-line healthcare professionals based on the guidelines of the Centers for Disease Control and Prevention (CDC), we all expect happy days in 2021. COVID vaccinations from companies like Pfizer and Moderna did promise to protect people against the deadly virus in clinical tests.

Moderna is said to be 94.5 percent effective, while Pfizer 95 percent successful in fighting against the coronavirus. In this article, we are going to discuss the two vaccines, their benefits, and possible side effects, if any. Read on to learn more.

Mike Giannulis talks about Pfizer and Moderna

Both Moderna and Pfizer are more than 94 percent effective; however, when it comes to their clinical trials, they are a bit different. As far as Pfizer is concerned, it prevented the virus in most except for eight out of the 18,198 participants, who were monitored for approx 60 days after they received the second dose of Pfizer.

When it comes to Moderna, it had five out of the 13,934 participants develop COVID-19 after they were monitored for approximately seven weeks after their second vaccination.

Both the vaccines proved effective for grown-up adults, though, Moderna proved 100 percent effective in people aged more than 65 years. Pfizer, on the contrary, was 93 percent effective in people aged 56 years and above.

What do the experts say?

The experts in the industry cited that Moderna, as well as Pfizer vaccines, are safe and effective, and therefore, front-line healthcare professionals are receiving the vaccination. Then, there are some instances of side effects of the vaccine, as Michael Giannulis has read. These side effects are leading to problems that will delay emergency use approval from the US Food and Drug Administration.

The side effects of the vaccines

The common side effect is a reaction on the injection site. The Pfizer vaccination is given in two doses and most of the side effects were reported after people received the second dosage.

The common side effects include reaction on the injection site (84 percent people reported this fact), headache (55 percent), fatigue (63 percent), fever (14 percent), muscle pain (38 percent), upset tummy (least reported side effect), and chills (least reported side effect).

These symptoms may lead to discomfort in a few people. Then, even flu shots have some mild symptoms.

Side effects are natural and would weaken

These are moderate side effects, to become weak; therefore, there is no need to worry much. No matter whether you have these symptoms after the initial dose, you will need to take the second dose to protect yourself from the coronavirus.

The side effects are temporary and pass with time. Therefore, it is not a matter of concern and not a de-motivating factor for people. The vaccine is safe.


When it comes to the coronavirus vaccine, you must listen to your doctor, whose focus is on your health and wellbeing. You need to stay updated as to what is happening around when people are taking the vaccine to fight COVID-19. Stay safe and healthy.
