Arizona Department of Health Services Director Dr. Cara Christ and Gov. Doug Ducey.

PHOENIX โ€” The stateโ€™s top health official says not enough Arizonans may be willing to take the COVID-19 vaccine, which first becomes available to high-priority groups next week, to achieve some sort of โ€œherd immunity.โ€

Ideally, Arizona will get to the 70% level of immunization, said Dr. Cara Christ. Thatโ€™s the bare minimum of what many in the medical community consider necessary to prevent widespread infection.

But Christ acknowledged Arizona has a certain number of people who are suspicious of all vaccines. And these are new vaccines, being permitted through an โ€œemergency use authorizationโ€ by the Food and Drug Administration.

Coronavirus vaccinations have begun in New York. Critical care nurse Sandra Lindsay at Long Island Jewish Medical Center in Queens got what Gov. Andrew Cuomo called the first shot given in the state's campaign to vaccinate front line health care workers.

On top of that, a survey said more than a third of the stateโ€™s health-care professionals who were polled said theyโ€™re unlikely to get a vaccine, even if itโ€™s approved by the FDA.

Christ, however, said she sees the numbers as โ€œpromising,โ€ as 55% of health-care providers surveyed said theyโ€™re likely to get the vaccine.

She also noted the survey, by OH Predictive Insights on behalf of the Arizona Department of Health Services, was done in the last half of November. Christ said she believes health-care professionals now have more information and their views about the vaccine may be changing.

But this isnโ€™t strictly about the attitude of doctors and nurses. The state health director said these medical personnel are among the โ€œtrusted sources of health informationโ€ for other individuals making decisions about getting a novel vaccine.

โ€œWe need to create a campaign using the most impactful messages aimed at those who have concerns or are unlikely to take the vaccine to increase the willingness to be vaccinated,โ€ Christ said.

Messages from someone who already took the vaccine are โ€œalso one of the best confidence boosters,โ€ she said. โ€œSo encouraging those who have been vaccinated to discuss the vaccination with their colleagues may help improve vaccination coverage.โ€

But the health chief said she is realistic in her expectations of how many Arizonans will go along.

Her best indication is the annual flu vaccine.

โ€œSometimes weโ€™ll fall anywhere between 37% and 50% of the population getting vaccinated,โ€ she said. โ€œIt may fall somewhere in there.โ€

There are other issues to consider even in encouraging medical professionals to get vaccinated.

One is that the vaccine itself has side effects, including causing a possible fever.

โ€œThatโ€™s your bodyโ€™s normal response to an infection,โ€ Christ said. โ€œAnd it does that when you get a vaccine.โ€

That could result in doctors and nurses, already in short supply, staying home after getting inoculated.

โ€œThat is a concern,โ€ Christ said. โ€œWeโ€™ve been working with our health-care partners discussing the need to stagger their health-care workersโ€™ (vaccinations). You probably donโ€™t want all of the emergency room physicians going in at the same time.โ€

Anyway, Christ said, no one wants a health-care worker with a fever showing up on the job, even if the suspected cause is the vaccine.

Separately, Christ expressed disappointment with some elected officials who not only do not wear masks but also have told people to ignore the advice of health-care professionals about covering up. Those specifically include Rep. Andy Biggs, R-Ariz., who has posted a series of anti-mask messages on the internet.

โ€œIt makes the messaging difficult,โ€ Christ said.

She said there are scientific studies that prove masks keep people who may not know they have COVID-19, because they have no symptoms, from transmitting the virus to those around them.

โ€œBut there are also studies that have scientifically proven that it protects me, by wearing my mask, in case anybody else is asymptomatic and could be spreading,โ€ she said.

Christ said anyone with questions should find โ€œreputable websitesโ€ for more information, including that of her own Arizona Department of Health Services; the U.S. Centers for Disease Control and Prevention; or local health departments โ€œto really get the facts and the data on masking.โ€
