        Understanding health risks and social effects of COVID-19

        Since March 2020, the novel coronavirus virus (hereafter coronavirus) has resulted in more than 660 million cases and 6.6 million deaths globally. Not being vaccinated increases your risk for COVID-19, the disease caused by coronavirus.
        According to the National Institutes of Health, even if you recover from COVID-19 in the short term, COVID-19 can
        • damage vital organs (ie, lungs, heart, brain)
        • increase your risk for COVID-19 long-term symptoms (ie, brain fog, a symptom similar to early dementia).

        • make you socially isolated and miss out on activities such as work, school, social activities. Participation in these activities is important for preserving mental health and overall well-being.
        • make you end up in the emergency department for care.
        • require a long hospital stay leading to high hospital and out-of-pocket medical bills.
        • be costly for you, your family, and your community.
        • Specific examples that directly relate to cost include
        • (1)public restrictions because of ongoing societal spread result in job loss
        • (2)limited resources for childcare, and
        • (3)increase need for community support to compensate for individual losses result in an overall societal cost.
        The new sub-variants are more infectious and can spread faster than older variants of the original coronavirus. You may not have symptoms of COVID-19, but you still can carry the virus and spread it to other people and animals.

        People with disabilities (PWD) may be at increased risk of contracting COVID-19 due to several reasons including limited mobility or inability to avoid coming into close contact with others who may be infected, need for close contact with personal attendants and caregivers, having trouble understanding information or practicing preventive measures, or inability to communicate symptoms of illness.

        Understanding COVID-19 Vaccine

        The misinformation about the vaccine on television and social media outlets can make you feel uncertain, scared, or vaccine hesitant.
        • A big reason for 40% of the population to remain unvaccinated is false information spread on the internet.
        • In 2021, a Kaiser Family Foundation report found about 80% of adults who say they will “definitely not” get the vaccine believe or are unsure about at least 1 prevailing COVID-19 vaccine myth.
        • Additionally, a majority of adults (54%) either believe some rampant misinformation about the COVID-19 vaccines or are unable to debunk it.
        • Fact checking (such as checking the source and credentials of the person posting) is a key strategy to verify the factual basis of the information.
        • Our vaccine guide is based on scientific evidence to help you make the right choice regarding staying up-to-date with vaccines and boosters.

        Common fears related to vaccine

        • There is no evidence any vaccines cause fertility problems in women or men.
        • However, getting COVID-19 can lead to male fertility problems, cause thyroid problems which can affect your menstrual cycle and fertility.
        • Pregnant people who get COVID-19 experience higher risk of preterm birth, low birth weight, and stillbirth.

        Health/social benefits

        Historical, social/economic benefits

        • 1.
          Vaccines have played a huge role to help eradicate other diseases such as smallpox from the world.

          The sooner a greater number of people are vaccinated, the better chance we have of keeping the new number of virus cases low in your community and return to work, school, travel, and eat in restaurants safely in-person which in turn can help our economy return to pre-COVID-19 era.
