The COVID Vaccine waiting to be used on people and giving them normalcy back

Elise Ravech, Writer

I am sure many of you have heard that after the long awaited quarantine, there have been vaccines starting to be developed. Below you will find all of the information out so far comparing the two highest rated vaccines.

Starting with the age rage, the Pfizer vaccine has been authorized on people 16 and older. When looking at the Moderna vaccine, they recommended people 18 and older. However Moderna has started testing the vaccine on an age group consisting of 12-17 year olds.

When comparing the results of the vaccine, Pfizer showed a higher result of 95% efficacy. This means that it was 95% successful at preventing COVID in someone’s body. They started measuring seven days after the second dose. The Moderna vaccine was close but came in lower at 94.1%. They started measuring from 14 days after the second dose.

These two vaccines both need two shots in order to work successfully. The Moderna vaccine second dose is needed 28 days after the first, the Pfizer second dose is required 21 days after.

An interesting note is that each shot of Pfizer has 30 micrograms of the vaccine. The moderna has 100 micrograms, essentially more of the virus in each shot. However Moderna isn’t getting better results than Pfizer.

The most common side effects are:

  • Injection site pain
  • Fatigue
  • Headache
  • Muscle Pain
  • Joint Pain

Occasionally some reported having a fever. These side effects are more common after the second dose is in the immune system. An important note is that younger adults have reported these symptoms.

It must be knows that these side effects are a good sign of our immune system preparing the help fight COVID. They do not by any means mean that the vaccine is unsafe or harmful.

If you are wondering when you will be able to get a vaccine of your own Governor Baker has put in place a three phase plan.

Phase one will include those 75 years and older starting to get the vaccine, this phase has already begun. It also include any healthcare workers, for them the vaccinations began in december.

The Three Phase Plan Governor Baker has put into place to keep Massachusetts safe 

Phase two will include everyone in early education grades kindergarten to twelve, grocery workers, transit workers, agriculture, restaurant and cafe workers, along with public works employees. This will begin in February and last until March, this is where the majority of the vaccinations will occur.

Phase Three includes the rest of the people like teachers, bottle beverage workers, veterinarians, funeral directors and workers. The state hopes to have this done in April through June.
