Experts argue other assertions made in the lawsuit filing are completely unsubstantiated, such as one claiming that vaccinated people were more likely to die from COVID-19, which Texas health data disputes.

The legislation, which Republican lawmakers have been trying to pass since 2021, offers no exceptions for doctors’ offices, clinics or other health facilities.

Long an opponent of vaccine and mask mandates, the Republican said pharmaceutical companies may have misrepresented data. Pfizer strongly disagrees.

Corbevax, a low-cost coronavirus vaccine created in Houston, could be a better weapon against COVID-19 by reaching the unvaccinated in poorer countries.

“The situation in Texas is that it probably won’t reach the peak [for cases] until the second half of January,” a top researcher said.

The state has already challenged the federal government’s vaccine orders for big businesses, health care workers and federal contractors.

In 2021, the Tribune’s data visuals team helped tell the biggest stories affecting Texans. Here’s a roundup of our most impactful work.

The highly contagious omicron variant has led to a sharp increase in COVID-19 cases in Texas. Hospitalizations are beginning to increase in a health care system already troubled by staffing shortages.

So far this month, at least 1.2 million Texans have gotten booster shots — nearly triple the number of people who received their first doses of the vaccine during the same time.

Untreated medical conditions, lack of access to testing and limited paid time off leave uninsured Texans particularly vulnerable to the disease.

Texas’ nursing home staff vaccination rates are lower than half the country’s — but a judge’s decision last week to delay a vaccine mandate helped them avoid laying off a third of their employees.

Early indicators suggest the variant is very contagious, but little is known about the severity of disease it causes.

So much is unknown about the new COVID-19 variant: the severity of the illness it causes, whether it can resist vaccines and natural antibodies and whether it’s more contagious than the delta variant that has burned through Texas and the U.S. for months.

Texas Attorney General Ken Paxton had called the mandate “an unprecedented federal vaccine decree” on health care workers.

A surge in COVID-19 cases from the West is impacting El Paso.

The approval marks a long-awaited milestone in the nearly two-year fight against the deadly virus that experts say has likely already infected nearly half the population in that age group.

The federal government will now send a first shipment of more than a million doses destined for children in that age group to providers in nearly half of the state's counties.

The vaccine’s protection goes down with time, so medical experts recommend a supplemental dose after two to six months. Find out here if it’s time to get one.

A Houston vaccine team would like a U.S. distributor but for now focuses its efforts abroad to inoculate those in countries where COVID-19 variants surface more quickly.

A prohibition on vaccine mandates was one of Gov. Greg Abbott’s priorities for the special session, but it did not have enough support in the Legislature.

The halt comes after Gov. Greg Abbott expanded his ban on COVID-19 vaccine mandates — which previously applied to cities, counties and school districts — to private employers.

American Airlines and Southwest Airlines say they will continue requiring employee vaccinations despite Abbott’s new order, which has left federal government contractors, nursing homes and other companies caught between conflicting rules from the Biden administration and the state.

About 40% of Texas nursing home workers are unvaccinated and could face dismissal or quit their jobs under a federal vaccination requirement for the industry.

More than 11% of those who received their first dose haven’t gotten a second shot, and more than 1 million people are more than 90 days overdue.

In the Texas Medical Center, and at more than a dozen hospitals throughout the greater Houston-Metro area, health officials say COVID-19 numbers are trending in the wrong direction.

The latest, most transmissible coronavirus variant is spreading rampantly in countries with low vaccination rates, and health experts are bracing for impact in Texas.

The first cruise sets sail from Galveston this weekend for the first time since the pandemic, but a Houston mom and her 8-year-old twin daughters won’t be on board as planned due to a mix-up over vaccination waivers.

In the June poll, 47% of voters said they were coming and going as they were before the pandemic, while 39% said they were leaving the house but exercising caution.

Their Texas swing is part of a larger effort by senior administration officials who are fanning out across the country this week to encourage vaccinations ahead of the administration’s self-imposed goal of hitting a 70% countrywide vaccination rate by July 4.

Worried about a possible resurgence of COVID-19 infections, doctors Carolyn Salter and her husband, Michael Gorby, have taken it upon themselves to get lagging vaccination rates up in rural East Texas.

The possibility that the vaccine won’t work — or that, as some worry, it could even hurt them — is a devastating blow after a year of sacrifice, isolation and waiting for protection against the virus.

Abbott's signature will mean that businesses that require so-called "vaccine passports" can't get state contracts and could lose state licenses or operating permits.

Lawmakers didn’t succeed in curtailing the governor's power during a disaster, but they did pass bills that prohibit so-called vaccine passports and ban the mandatory closure of churches and gun stores.

Gov. Greg Abbott encouraged “groups of Texans who wish to get vaccinated as a business, family unit, friend group, or more” to schedule an event.

In the days since the federal approval of the shot for their age group, about 6% of Texas children ages 12-15 have gotten a dose of the Pfizer vaccine.

In a period of sagging vaccination rates — particularly among staunch conservatives — state Sen. Bob Hall used his platform to promulgate debunked anti-vaccine conspiracies and push claims that have largely been eschewed by the medical community.

The announcement will likely give new life to the debate about requiring vaccinations that has been playing out in Texas and across the nation.
