The Texas attorney general announced a lawsuit against Pfizer based on the claim that the company “unlawfully misrepresented” the effectiveness of its COVID-19 vaccine. The official specifically cites Pfizer’s reporting of clinical trial data showing 95 percent efficacy based on relative risk reduction compared to the control group as “misleading.” Notably, the lawsuit claims more vaccinated people are dying from COVID-19 than unvaccinated people based on cherry-picked U.K. data from four weeks in late 2021 and early 2022.
Recommendation: The high-profile nature of the claims increases their risk. Highlighting that, according to experts, the claims in the lawsuit are not scientifically sound is recommended. Debunking talking points may emphasize data from the Texas Department of Health and Human Services that directly contradicts the lawsuit’s claims about COVID-19 vaccine effectiveness. Data from January to October 2021 shows that unvaccinated Texans were 20 times more likely than vaccinated Texans to die of COVID-19. Additional data from the same period found that vaccinated people accounted for only 8 percent of all COVID-19 deaths. As of April of this year, unvaccinated Texans are 11 times more likely to die of COVID-19 than those who are up to date on their vaccinations. Messaging may also explain that the lawsuit makes several false assumptions, namely conflating vaccine efficacy in clinical trials with effectiveness in real-world settings and assuming that absolute risk reduction is a more accurate measure of vaccine efficacy than relative risk reduction. Fact-Checking Source(s): Austen American-Statesman, Texas Tribune, Newsweek Talking Points Are COVID-19 vaccines safe? More than 150,000 people participated in U.S. vaccine clinical trials, and almost 700 million vaccine doses have been safely administered in the U.S., with rare instances of adverse reactions. To ensure the continued safety of COVID-19 vaccines, data from clinical trials will continue to be collected for two years after each vaccine is first administered to ensure that they are safe over the long term. As with all vaccines, there will be ongoing monitoring for adverse events among people who are vaccinated in the future. What is the risk of having a severe adverse reaction to the COVID-19 vaccine? Severe adverse reactions after vaccination are extremely rare, but can cause long-term health issues. Rare adverse events – such as anaphylaxis and other allergic reactions, blood-clotting syndromes, heart inflammation, autoimmune diseases impacting the nervous system, and death – have been identified and investigated for legitimacy through the Vaccine Adverse Event Reporting System (VAERS). How were the COVID-19 vaccines developed so quickly? The process included the same rigorous safety reviews that are required for all new vaccines. Scientists were able to develop the vaccines quickly, safely, and effectively because the urgency of the pandemic created greater access to research funding, reduced bureaucratic obstacles, and encouraged unparalleled levels of government and industry cooperation. As new variants appear, vaccine researchers will continue to develop updated COVID-19 vaccines, also called “boosters,” to provide the highest level of protection against the virus. Does the COVID-19 vaccine increase risk of miscarriage? Studies show that miscarriages are a common outcome of a typical pregnancy, impacting 11% to 22% of all reported pregnancies. However, there is no evidence to show that pregnancy risks or complications, such as miscarriage, preterm delivery, stillbirth, or birth defects, are increased because of the COVID-19 vaccines. Data do show that experiencing a COVID-19 infection during pregnancy increases the risk of delivering a preterm or stillborn infant. For this reason, vaccination is critical to protect the pregnant person and the infant from negative health outcomes. COVID-19 vaccination provides antibodies to the pregnant person and the baby, protecting them both from the increased risk of serious illness. Why is it important to continue to collect data about COVID-19 cases? Are case counts accurate? COVID-19 case counts and deaths are key public health indicators, but experts agree that the number of COVID cases are likely undercounted and underreported. Case counts vary because of reporting barriers like the convenience of at-home rapid antigen testing and varied access to COVID-19 testing and diagnosis. COVID-19 death reporting is less burdened by the previous barriers but can be impacted by the timing lags in data entry across many systems of monitoring. The CDC COVID Data Tracker is a collaborative hub of COVID-19 monitoring information informed by state and county reports from hospitals, healthcare providers, and laboratories. The CDC makes this data publicly available and reports national COVID-19 data to the World Health Organization, as required under international health regulations. The current key indicators – COVID-19 test positivity, emergency department visits, hospitalizations, and deaths – help reveal COVID-19 trends across the nation. The National Center for Health Statistics also updates national statistics guidelines to ensure increased specificity and accuracy of COVID-19 death reporting. The cause-of-death determination guidelines distinguish COVID-19 and post-acute COVID-19 syndrome (PACS) as either an immediate or underlying cause of death on death certificates and medical reports. These updates help to clarify if people are dying from COVID-19 illness as an immediate cause of death, or with a COVID-19-related illness or condition as an underlying cause of death. 
Talking Points and Answers to Tough Questions
Yes, COVID-19 vaccines are safe. The COVID-19 vaccines have been tested and monitored for safety more than any previous vaccine in U.S. history. All COVID-19 vaccines have been rigorously tested and reviewed for human safety through a three-phase clinical trial process.
The risk of having a serious adverse reaction to the COVID-19 vaccine is very low—far lower than the risk of contracting COVID-19.
Common reactions to COVID-19 vaccination include mild side effects, such as limb soreness, fatigue, low-grade fever, headaches, and chills, which typically resolve within a few days.
It’s true that these specific vaccines were developed more quickly than previous vaccines, but their development built upon many decades of work on coronavirus vaccines and mRNA technology.
No, getting a COVID-19 vaccine does not increase the risk of miscarriage. To date, no monitoring system or studies have identified any association between miscarriage and COVID-19 vaccination.
Accurately tracking the spread of COVID-19 helps federal, state, and local decision-makers allocate critical emergency response funding and develop public health guidance.
