How should these medications decrease immunization viability"Immunizations work by encouraging your insusceptible framework to perceive a particular danger so it can react properly in the event that it at any point sees that danger once more,". 

Nonetheless, as indicated by Wallace, immunosuppressive medications work by lessening the capacity of your invulnerable framework to perceive and ward off dangers. 

This concealment is valuable in dealing with immune system conditions like rheumatoid joint inflammation, where an unwanted resistant response is happening. 

"However, immunosuppression additionally decreases the safe framework's capacity to mount a reaction to things you need it to react to, similar to contaminations and immunizations," she said. 

"We're beginning to understand that individuals ingesting immunosuppressive medications may have a more slow, more fragile reaction to COVID inoculation."

How might these drugs reduce vaccine efficacy?

“Vaccines work by teaching your immune system to recognize a specific threat so that it can respond appropriately if it ever sees that threat again,” said Wallace.

However, according to Wallace, immunosuppressive drugs work by reducing the ability of your immune system to recognize and fight off threats.

This suppression is useful in treating autoimmune conditions like rheumatoid arthritis, where an undesirable immune reaction is occurring.

“But immunosuppression also reduces the immune system’s ability to mount a response to things you want it to respond to, like infections and vaccines,” she said.

“We’re starting to realize that people taking immunosuppressive drugs may have a slower, weaker response to COVID vaccination.”

What can we do mitigate this problem?

Experts say there may be strategies we can use to get around the problem presented by immunosuppression.

Wallace suggested that some may be able to pause their medication around the time they get their vaccination or delay an IV infusion until they’ve had time to mount an immune response to the injection.

Dr. Meghan Baker, a hospital epidemiologist who works with immunocompromised patients at the Dana-Farber Cancer Institute and Brigham and Women’s Hospital, added that if there is flexibility in the timing of immunosuppressive therapies, experts often recommend completing the COVID-19 vaccine series at least 2 weeks before starting the medications.

If this is not possible, however, they recommend that patients speak with their personal physician about the risks versus benefits of delaying therapy.

Wallace further explained that specific recommendations regarding the timing of immune-suppressing medications would have to be tailored to the needs of the individual.

“For example, if someone is on chemotherapy to treat an active cancer, the risk of temporarily stopping that treatment is much different than the risk of stopping a medication that someone’s been on for 10 years to treat their stable rheumatoid arthritis,” Wallace said.

She also pointed out that different immunosuppressive drugs may affect vaccine response differently.

“So, guidelines that make sense for certain conditions or medications, may not be appropriate for others,” she explained.

In addition to making changes in medication timing, Wallace said, “There are also some studies looking at the effect of a ‘booster shot’ in this population, an extra dose given several months after the person is first vaccinated.”
