Some schools across the U.S. temporarily suspended their classroom activities.

The closures reportedly came as a result of side effects teachers experienced following their inoculation with the COVID-19 jabs registered in the U.S.

Edwardsburg Public Schools, located in Michigan, were allegedly among the first ones to close their operations due to vaccine side effects.

The Schools Superintendent Jim Knoll said on 16 News Now that some teachers experienced a wide range of side effects, including fatigue, fever, nausea, and vomiting.

The classes at the school system had to be quickly canceled on Monday, just two days after teachers’ vaccination.

Something similar occurred at the Northeast Ohio school district.

Fox 8 reported that a few days after the inoculation with their first vaccine doses, several employees experienced debilitating side effects that prompted the school officials to suspend classes for the time being.

NBC Connecticut reported that Colchester Elementary School in Connecticut was closed in a similar fashion since there were no replacements for teachers who suffered from vaccine-related side effects.

School Superintendent Jeffrey Burt said 17 workers, including nine core-subjects teachers, experienced side effects after receiving a single-shot Johnson & Johnson vaccine.

Burt listed fever and pain as the most common side effects that prevented teachers from coming to work.

Not an isolated case

Grayson County Public Schools in Virginia and Sandy Creek Schools also had to close their doors.

Moreover, Farwell School district in Michigan was closed on Wednesday to allow its employees to recover from vaccine-related symptoms school officials described as '’unpleasant’’ in a social media post.

Stark County schools also had to pause their classes on Monday.

Fortunately, enough staff members managed to recover from the vaccine side effects, enabling schools to resume their operations on Tuesday.

Newark City Schools in Ohio and Shepherd Schools had to suspend their classes as well.

Like others, some teachers from these schools felt ill after the inoculation.

Shepherd Schools superintendent Greg McMillan wrote that Thursday would be a non-working day that would not be compensated by online teaching.

Ithaca Public schools even announced temporary closures due to its predictions that too many of its workers would experience side effects from the vaccine.

Vaccination campaign continues

Despite the various side effects experienced by COVID-19 vaccine recipients, the U.S. vaccination campaign is expected to continue without delay.

So far, nearly 83 million Americans received at least one dose of jabs produced either by Pfizer, Moderna, or Johnson & Johnson.

Amounting to around 25 percent of the U.S. population, this number puts the the first place in the world as measured by the number of people vaccinated metric.

Yet, most vaccine recipients experienced some side effects, ranging from the mild ones to those more serious that prevented people from coming to work.
