Doctors from LMH Health and the University of Kansas Health System said Wednesday that they expect the COVID-19 vaccines to last six months to a year — or longer.
On Sunday, the Journal-World reported that local infectious disease doctor Jennifer Schrimsher said the vaccines should work for at least three months. This week, Schrimsher noted that she expects the vaccine protection to last “well beyond that.” Schrimsher said she expects the Moderna vaccine to be effective anywhere from six months to a year.
“Moderna recently released additional data on antibody response to their vaccine,” Schrimsher wrote in an email to the Journal-World. “While this data reported stops 90 days after the second dose, the antibody levels in those vaccinated are (1) higher than those who have recovered from active infection and (2) appear to persist well past 90 days.”
On Tuesday, CNN reported that Moderna’s chief medical officer told the JP Morgan 39th Annual Healthcare Conference that the company believes its vaccine should protect people against COVID-19 for at least a year.
Kathy Colson, a retired public health nurse who began working for the health department during the pandemic, said that while it is great to receive more positive information about the new vaccines, “We will wait for confirmation from FDA, CDC and KDHE on the research that supports this new information.”
According to an infectious disease physician at the University of Kansas Health System, the Pfizer and Moderna vaccines are expected to have a similar length of effectiveness.
“They are very similar in efficacy and safety profile and we would expect them to be in durability as well,” said Dana Hawkinson, who is also medical director of infection prevention and control.
Hawkinson said that while it is not yet assured exactly how long the COVID-19 vaccines will work, “most of the clinical and scientific community expects immunity from vaccination will be durable lasting six months to a year or more.”
In other vaccine news, Unified Command has set up two alert systems for community members to receive notifications about Douglas County vaccine information. The notifications will alert people of transitions to new vaccination phases, as well as provide information about how people who are eligible in that phase can sign up for a vaccine.
George Diepenbrock, spokesperson for Lawrence-Douglas County Public Health, specified that Unified Command does not yet have a way for people to sign up for vaccines in Phase 2 or beyond, but that the alerts would be another way to disseminate that information to citizens once it’s ready.
People can sign up for text or email alerts through Lawrence-Douglas County Public Health via bit.ly/VaccinationAlertLDCPH. People can also receive the alerts though Douglas County Emergency Management via dgcoks.org/emalerts. The alerts through emergency management can be sent via text, email or phone calls.
The two alert systems will include the same information, Diepenbrock said, so people will only need to sign up for one alert.
