Authorities are warning of a fresh and specific increase in counterfeit COVID-19 vaccination cards on the online market, according to a new law enforcement bulletin obtained by ABC News.

A blank template imitating the CDC-issued COVID-19 vaccination record card has been circulating on various social media platforms, including an anti-vaccine Telegram channel, the internal notice says. 

These blank cards can be downloaded, printed and filled out in order to gain entry where proof of vaccination is required, and to "satisfy employer vaccine mandates," according to the notice.

This latest warning comes just as ABC News has reported exclusively that federal health officials are seeing an alarming rise in the demand for these fraudulent cards, which cyber experts and federal officials are are concerned is a burgeoning and rapidly evolving market.

The illicit niche industry for forged cards is hitting its stride just as new vaccine requirements are rapidly being implemented at the federal, state and local levels and in both the public and private sectors -- requiring proof of inoculation in order to work at a hospital, teach or attend school, work out at the gym, or eat inside a restaurant.

Despite new policies and FDA full approval of Pfizer's COVID-19 vaccine, some hesitant Americans still refuse to be vaccinated.

For enterprising fraudsters, the fresh demand presents a ripe opportunity. 

In this latest bulletin, social posts and law enforcement source information indicate that criminal actors in the Philadelphia area are "profiting from the production of these cards" and "selling the counterfeit cards through online and in-person sales."

"The PDF being shared on local Telegram channels offers limitless access to counterfeit vaccination cards," authorities warn. 

"The use of fraudulent cards may have a significant impact on public health, especially in compact and vulnerable communities like academic institutions and healthcare facilities," the bulletin warns, reminding those who profit from or use these fake cards may face prison time or hefty fines.

The U.S. Department of Education has launched a civil rights investigation into five states that have barred indoor making mandates, alleging that the governors are creating an unsafe learning environment for students with disabilities at heightened risk of severe illness from COVID-19.

It’s an aggressive new legal tact from the Biden administration to challenge Republican governors who insist indoor mask mandates don’t work.

The Centers for Disease Control and Prevention has found that schools are generally safe if students and staff universally wear masks. School districts that struggled with COVID-19 outbreaks this year – often sending thousands of kids home – typically did not require masks.

The investigation's focus is on Iowa, Oklahoma, South Carolina, Tennessee, and Utah. The Education Department says it is not including Florida, Texas, Arkansas and Arizona at this time "because those states’ bans on universal indoor masking are not currently being enforced as a result of court orders or other state actions," federal documents state.

The benefits of getting a COVID-19 vaccine outweigh the risk of getting myocarditis from the vaccine, CDC experts say, adding that it's even more apparent now that cases are spiking among young people.

The risk of getting myocarditis - inflammation from the heart muscle – from the virus is much higher than getting it from a vaccine, scientists said at a CDC advisory panel Monday, pointing to new data.

The CDC estimates that the risk of myocarditis for the highest risk group -- young males age 16 to 17 -- is about 73 cases per million doses of the Pfizer vaccine. 

The public health agency also estimates that 56,700 cases of COVID-19 would be prevented in that same age group for every million vaccines. 

In addition, the risk of myocarditis after actually getting COVID-19 is six to 34 times higher than it is from getting a vaccine.

As of Aug. 29, dozens of states were reporting limited beds in intensive care units, with 23 states reporting over 80% capacity and six states reporting over 90% capacity, CDC experts announced at an advisory panel Monday.

The panel also found that the risks of contracting COVID-19 are still much higher for the unvaccinated.

People between ages 18 and 49 are 24 times more likely to be hospitalized if unvaccinated, according to the CDC, 19 times higher for unvaccinated populations between 50 and 64 and 13 times for unvaccinated people 65 and older.
