We have dealt with many uncertainties in 2020, not the least of which is the worldwide pandemic caused by SARS-CoV-2 (COVID-19) virus, and subsequently we anticipate many more uncertainties in 2021.†As of this writing, there is no known medicinal therapeutic cure for SARS-CoV-2.†Our best defense is changing habits and behaviors that lead to the spread of infections such as SARS-CoV-2.†With the new development of a vaccine, there is light at the end of this long and grueling tunnel.†However, it will take time to see effective rollout and thus achieve herd immunity.††At the same time, we still have a well-known ìcertaintyî that we face every fall and winter: the influenza virus. Influenza (aka flu) spreads much the same way that the COVID-19 virus spreads: respiratory droplets.†We have several ways of mitigating the spread of infections such as good hand hygiene, coughing into oneís elbow, wearing masks, social distancing and staying home and isolating if sick. For both influenza and SARS-CoV-2, there are even medications that can be given in the event of an active infection.†However, most are not truly ìcurative;î therefore, they are only prescribed to alleviate symptoms and prevent further complications.††Flu season can last into MayFlu season typically ramps up in the United States from fall to winter every year, lasting as late as May and†peaking from December to February.†Every year, the Centers for Disease Control collects data associated with influenza.†For our latest completed flu season data (2019/2020), the CDC showed that the influenza virus led to 38 million illnesses, 18 million medical visits, 405,000 hospitalizations and 22,000 deaths.The flu vaccine saves livesThankfully, we have a vaccine for the influenza virus, and it is effective in preventing the spread and severe sickness from the flu. It is not 100% perfect; however, it gives a level of protection that no other therapeutic medication or change in behavior can give. The flu vaccine liberates us from having to worry about social distancing and economic shutdowns, like our experience with the COVID-19 virus.Simply put, the flu vaccine saves lives! It is estimated that in the worst of flu seasons the flu vaccine could save up to 61,000 lives if 40% of the population receives the vaccine at only 20% effectiveness.††Millions of flu vaccines are administered throughout the United States and the rest of the world each year.†As of Dec. 4, 2020, there were 189.4 million flu doses distributed throughout the country. This is the highest number of single flu doses distributed in the United States during a single influenza season ever.Get your flu vaccineIn a year of uncertainty, make sure one thing is certain for you and your family: Get your flu vaccine.†Protect yourself and those around you from catching the flu, especially those at an increased risk for severe complications.†Frequently asked questions1. Why do I have to get a flu vaccine every year?Influenza virus mutates heavily from season to season and is therefore very good at getting past our bodyís immune defenses.†The flu vaccine changes from year to year to account for these mutations. Additionally, whether we have antibodies from a vaccine or from active infection, our immune response only lasts for about three to six months. There are also generally four different flu strains that circulate every year, so even if you catch one strain you could still catch any of the other three.2. What are the side effects from the flu vaccine?The most common side effect from any vaccine is a soreness around the injection site.†This usually goes away within a few hours to a day. Other side effects such as a headache or a low-grade fever can occur as well. Before any vaccine is administered, the medical professional should obtain a targeted history assessing for any avoidable potential complications.3. Are there different doses based on age?†Yes! There are two different doses based on age. Patients who are 65 years plus have the option for a more concentrated dose.†A recent study of 30,000 participants age 65 and older showed that the high-dose flu vaccine had 24% fewer influenza illnesses compared to those who received the regular dose.3. Should everyone get the flu vaccine?Most people can safely receive the flu vaccine.†Those who should not are those with a past severe allergic reaction to the flu vaccine. If you are uncertain if the flu vaccine is safe for you or right for you, contact your doctorís office and ask.
