Common Myths About Flu Immunization – It’s Time to Have an Honest Talk

Dear LA County Community,

Influenza (“flu”) season in Los Angeles County runs from October to the end of March 2020, and this season could be a particularly bad one. Despite many studies proving immunization as the best defense against catching the flu, many people still avoid this defense because they believe the myths associated with getting vaccinated. So, this month, I’d like to share some of the more common falsehoods about the flu vaccination, in hopes that this year, EVERYONE who is medically able, will protect themselves and their loved ones, and get immunized.

“It’s too early for flu immunization.”

  • While it may feel too early to think about the flu, the U.S. Centers for Disease Control and Prevention (CDC) recommends that vaccination occur before the onset of influenza activity in the community to ensure the best protection against the virus.
  • The flu immunization, like other vaccines, works best through what is called “herd immunity,” meaning the more people that get the vaccine the less the disease is to spread.
  • Children ages six months to eight years, who require two doses of the flu vaccine, should get their first immunization as soon as possible after the vaccine becomes available, because they are particularly susceptible to serious flu complications. LA County experienced its first flu death this month, a stark reminder that getting vaccinated early can save lives.

“I am healthy and don’t need the flu immunization.”

  • Anyone can get the flu, and serious problems related to the flu can happen at any age. Flu deaths have been recorded in otherwise healthy young adults.
  • People 65 years and older, anyone of any age with certain chronic medical conditions (such as asthma, diabetes, or heart disease), pregnant women, and children younger than 5 years face higher risk of developing serious complications if they get sick with the flu.
  • When healthy people get immunized, they keep those around them healthy as well.

“I can get the flu from taking the flu vaccine itself.”

  • The virus in the flu vaccine is not active, which means that you cannot get the flu infection from immunization. Mild side effects, including soreness, headaches, fever and nausea, may occur in some people after immunization. These are short term effects of your body mounting an immune response and should not be mistaken for an onset of the flu.
  • While the flu vaccine protects you against the worst of the worst, sometimes you may still be susceptible to less severe viruses.

“The flu vaccine causes autism.”

  • The Centers for Disease Control (CDC) has thoroughly studied this issue and has found no link between vaccines and autism.

“I got the flu immunization last year, I don’t think I need it again this year.”

  • Each year the flu season is different, and the strains of the flu are different from year to year. It is important to be protected each year against the most recent flu strains that could otherwise cause serious illnesses. Th CDC recommends routine annual flu vaccination to address these seasonal changes.

Additional Steps

While the flu vaccine remains the best defense against the flu, you can take additional steps to help protect yourself and your family from the flu and other viruses. Those steps include the following:

  • Wash your hands often and thoroughly with soap and water.
  • Use an alcohol-based sanitizer on your hands if soap and water aren't available.
  • Avoid touching your eyes, nose or mouth whenever possible.
  • Avoid crowds when the flu is most prevalent in your area.
  • Practice good health habits.
  • Get plenty of sleep, exercise regularly, drink plenty of fluids, eat a nutritious diet and manage your stress.
  • Stay home if you do get sick.

As a physician and a parent, I hope that debunking these common misperceptions encourages everyone to do what’s best for themselves and their families and get immunized today.

To your good health,

Muntu Davis, MD, MPH

09/08/15 - Prescription drugs play a critical role in treating people when they are sick or feel pain. It is also very important to properly dispose of all unused or expired medications. Unused medication can pose a major health and safety risk if left in the home.

08/10/15 - Last Thursday the California Department of Public Health (CDPH) announced a case of human plague in California. The patient lives in LA County and was hospitalized for the illness after a family trip to Yosemite State National Park and Stanislaus National Forest. Officials are still investigating where the individual may have contracted the disease.

07/06/15 - I am happy to report that new Ebola cases in West Africa have significantly declined due to the extraordinary efforts by healthcare professionals to care for infected individuals and reduce community transmission. The number of new weekly cases in West Africa has remained below 30 for several weeks and efforts remain strong to bring the epidemic to a closure as soon as possible.

04/22/15 - Progress continues to be made as the world responds to the Ebola epidemic in West Africa. Although the situation has improved greatly and the weekly number of new cases has fallen well below 100, we must remain vigilant until the number of new cases in affected countries reaches zero. Here in Los Angeles County, we continue to closely monitor individuals who travel here from affected countries and who may be at risk of developing Ebola.

03/17/15 - The world response to the Ebola epidemic in West Africa has decreased the number of new cases occurring there and there is hope that the epidemic can be stopped sometime this year. Here in Los Angeles County, we continue to closely monitor individuals who travel here from affected countries and who may be at risk of developing Ebola. We maintain our surveillance and actively monitor a small number of travelers each day who have

11/24/14 - Earlier this week the Centers for Disease Control and Prevention (CDC) added Mali to the list of Ebola-affected countries, which continues to include Guinea, Liberia, and Sierra Leone. To date, more than 15,000 individuals have contracted Ebola during this latest epidemic and there have been 5,420 related deaths worldwide. In the United States, a second Ebola-related death occurred last Monday after Dr. Martin Salia was transferred to Nebraska Medical Center from Sierra Leone for medical care following several days of illness. His tragic passing highlights the critical importance of early intervention and care in recovery.

11/17/14 - Ebola outbreaks continue to affect Guinea, Liberia, and Sierra Leone in West Africa with some new cases reported in Mali. While the rate of new cases in Liberia and Guinea has leveled off, the rate of rise in Sierra Leone continues to accelerate. To date, approximately 14, 000 individuals have contracted Ebola during this latest epidemic and there have been 5,160 related deaths worldwide. The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) will continue to monitor the situation and coordinate relief efforts to control the spread of infection. It is important to note that only two cases of Ebola have been exported from West Africa to other parts of the world, which is a testament to the effectiveness of the strategies that are in place to prevent spread. Those two cases are, of course, the case that was diagnosed in Dallas on September 30, and the more recent case in a physician in New York City who has recovered and been released.

11/10/14 - The Department of Public Health continues to coordinate efforts to ensure we have an effective strategy to respond to a potential case of Ebola in LA County. As part of these ongoing efforts, we met last week with the Hospital Association of Southern California and the California Association for Health Facilities. The meetings were held jointly with LA County Emergency Medical Services and provided hospitals and long-term health care facilities with an update on Ebola, our current activities, and response plans for LA County. Each meeting was an opportunity to strengthen partnerships and facilitate coordination with all health care providers who may play a role in identifying and treating an individual with Ebola.

11/4/14 - The State Health Officer from the California Department of Public Health recently issued a risk-based quarantine order for any individuals coming into California who had contact with a person confirmed with Ebola in Liberia, Sierra Leone, or Guinea. The Los Angeles County Department of Public Health will comply with the State’s order.

10/21/14 - As the news continues to evolve around Ebola, I want to reassure all residents in Los Angeles County that, to date, there are no suspected or confirmed cases of Ebola in Los Angeles County. This past week, we have worked diligently to update and strengthen our plans to address Ebola. We are more prepared today than we were yesterday, and we will be more prepared tomorrow than we are today.
