What Kind of Vaccines are required by OSHA for employees

During the 2017-2018 flu vaccine season, the effectiveness of vaccination against influenza A and B viruses was %40. The statistics for this year are believed to be higher.

Most of the contagious diseases spread in public places/workplace can be prevented by vaccines. Vaccination has proved to be the most effective way in the battle against some diseases such as smallpox.

As the structure of viruses changes over time, you need to be updated and get vaccinated annually against some viruses.

But what are the most common illnesses in the workplace? When should you get/avoid vaccines? Are there any possible dangers related to vaccination?

In this blog, we try to cover the most frequent questions asked by our clients at Southern Nevada Occupational Health Center (SNOHC) about vaccination.

What is vaccination?

Vaccination is a form of treatment that enforces the body against a particular infection. It involves injecting a weak type of the virus/bacteria into the body to stimulate the immune system and help it in the fight against the real viruses.

The first successful vaccine was developed by Edward Jenner in 1796. He demonstrated immunity to smallpox by injecting a vaccinia virus (cowpox) into a boy.


Required vaccines for employees

According to OSHA, some vaccines are required and recommended for employees. Vaccines help you to be protected from diseases. When you receive a specific dose of the vaccine, the body releases antibodies, making you immune to the disease. Some vaccines need to be renewed after some years, but some need to be repeated yearly.

Adults over 65, pregnant women, young children, those who suffer Asthma, diabetes, cancer, HIV/AIDS, heart disease & stroke, and children with Neurologic Conditions are mostly considered as people at high risk. This vaccine is not mandatory in the USA because some employees may be medically unable to receive the flu vaccine.

People born in 1957 or after that, might be considered immune to MMR if they can provide the confirmed documents of immunity or appropriate vaccination against MMR.

People who work in medical facilities should be immune to MMR. These people should have two documented doses of MMR. Two doses of MMR vaccine should be considered for unvaccinated people born before 1957 who do not have confirmation for immunity to measles or mumps, and one dose of MMR vaccine should be considered for people with no laboratory evidence of disease or immunity to rubella.


Varicella Vaccine (Chickenpox)

Varicella Vaccine is for protection from Chickenpox. Chickenpox is a viral disease caused by the varicella-zoster virus (VZV); it can easily get spread in the air by sneezing, coughing, or by direct contact with infected blisters, saliva, or mucus.
