Colin Powell’s death does not mean vaccines are ineffective, experts say

Area doctors explained that former U.S. Secretary of State Colin Powell’s death last week from complications of COVID-19 although he was fully vaccinated is not evidence the vaccines don’t work.

Powell was 84 and battling blood cancer, making him high risk for the vaccine not fully protecting him and for dying from even a mild case of COVID-19.

Unvaccinated Ohioans have made up 98% of statewide COVID-19 deaths in 2021, according to the Ohio Department of Health.

Local doctors say stopping the virus from spreading is key to protecting vulnerable people and that requires everyone to get vaccinated.

Readers continue to ask questions about the coronavirus pandemic, including many questions about vaccines’ efficacy and safety. So this news organization assembled a panel of trusted local experts, including doctors and pharmacists, to answer your questions on a regular basis. Here are answers to some of the questions we’ve received from readers in recent weeks.

Local experts quoted in this article are:

  • Dr. Roberto Colón, chief medical officer at Premier Health’s Miami Valley Hospital.
  • Dr. Michael Klatte, chief of infectious disease at Dayton Children’s Hospital.
  • Dr. Jeffrey Weinstein, patient safety officer at Kettering Health.

Q: Colin Powell was fully vaccinated against COVID-19 but he still died of coronavirus. Does that mean the vaccines are ineffective?

Colón: Unfortunately, no vaccines are 100% effective and sadly, this is an example of an infrequent occurrence of vaccinated individuals who do not survive an infection. Patients with weakened immune systems such as persons undergoing treatment for cancer are more susceptible to these breakthrough infections because the protection achieved from vaccines is either lower than in healthy individuals or weakens faster than other people.

Weinstein: Vaccines are highly effective at preventing COVID-19 infections and even more effective at preventing hospitalization and death. In Colin Powell’s case, he was at high risk due to his age (84) and underlying diagnosis of cancer, which factored into his death.

Q: If the coronavirus vaccine is effective, why do the vaccinated care if others choose not to be vaccinated?

Klatte: We know that unvaccinated individuals are much more likely to be infected with COVID-19 compared to those who are vaccinated. The longer the virus circulates in the population and the more people it’s able to infect, the greater the odds are that it develops genetic mutations, allowing it to evade immunity produced by immunization (as well as immunity generated by prior infection). The more genetic mutations the virus develops, the greater the possibility of the virus also developing resistance to our currently effective treatments. Stopping the virus from circulating is key — and this is best achieved through vaccination.

Colón: Because these vaccines are not 100% effective, being exposed to more infected individuals in the community increases the exposure unnecessarily. This is particularly significant to our older individuals and those with weakened immune systems who may be more likely to have breakthrough infections. Additionally, having people remain susceptible to infection because they have not been immunized raises the risk of another variant emerging that could be more likely to evade protection from vaccines or previous infections. The goal should be to ensure as many people are immunized against COVID-19 as quickly as possible.

Q: If coronavirus vaccines are effective, why are additional/booster shots recommended?

Weinstein: Through time, the effectiveness of many vaccines wane and then booster shots are required. The tetanus vaccine is a good example — booster shots are needed every 10 years. Currently, booster doses of the COVID-19 vaccines are recommended for certain age groups and at-risk groups because the protection may be less after many months.

Klatte: The primary goal of vaccination is to prevent severe disease, hospitalization and death due to COVID-19. Preventing symptomatic illness and preventing infection entirely are secondary aims of COVID-19 vaccination. During the time between when COVID vaccines were first made widely available to the public and now, we’ve seen the emergence of the highly infectious Delta variant. We’ve also seen gradually decreased vaccine effectiveness against prevention of symptomatic illness in people who were vaccinated earliest — including health care and other essential workers, people over 65 years of age, and those with underlying risk factors for severe disease. There has also been a small increase over time of the number of people over 65 years who were vaccinated earliest and who have been hospitalized due to COVID-19 infection. For otherwise healthy individuals under 65 years, the initial vaccination series continues to provide excellent protection against severe disease, hospitalization and death.

Colón: The need for boosters is not uncommon with vaccines. Many of us have been getting routine boosters since our childhood. Boosters are needed when the amount of protection decreases over time and are necessary to act as a reminder to our immune system to maintain protection, against COVID-19 in this case.

Q: There are no long-term studies of these coronavirus vaccines. How can I be sure they are safe?

Colón: mRNA vaccines have actually been studied for decades and long-term risks have not been identified. Even with other vaccines, the risks and problems are manifested immediately or in a short time. Vaccines do not have side effects or problems that develop months or years after administration.

Klatte: When one includes participants in the original Pfizer, Moderna and J&J vaccine trials, we now have data on the safety of these vaccines dating back more than 18 months. Billions of people across the globe have safely received Pfizer, Moderna or J&J vaccinations against COVID-19. The U.S. safety monitoring intensity of these vaccines is unprecedented in our nation’s history.
