Are COVID-19 Vaccines Effective?

COVID-19 vaccines have effectively reduced casualties and hospitalizations caused by the virus around the world. The vaccine works by decreasing the body’s natural infection rate by developing the body’s natural defenses to the virus. The response protects the body from a severe or deadly infection. Without the vaccine, there would be more deaths and severe illnesses. Although scientists are still researching the vaccine, there are clear benefits to getting vaccinated. Investors should consider the implications of the vaccine in affecting market volatility and thus share trading as CFDs. Companies like Pfizer and Moderna could continue to outperform in the stock market, however the biotech sector has come under pressure as the Nasdaq 100 tumbled during January of 2022. The news that Moderna received full approval from the FDA to use their vaccine in people 18 and older could help its bottom line.

The vaccine is necessary for several reasons. First, they reduce severe illness, casualties, and hospitalizations caused by the virus. Second, even with breakthrough infections, symptoms of vaccinated people are typically milder than those of unvaccinated people. Third, the vaccines are protective against many new variants. Fourth, the vaccines are proven to be safe and tested.

How the Vaccine Works

Pfizer-BioNTech and Moderna make messenger RNA or mRNA vaccines. These vaccines do not put a weakened virus into people’s bodies. Instead, they use an mRNA substance created in a laboratory that tells our cells to make a spike protein. This protein is on the surface of the virus that causes COVID-19. Then our body produces antibodies against the protein to fight it off. These antibodies fight off COVID-19 when the virus enters the body.

Vaccines Reduce the Risk of Hospitalizations and Death

COVID-19 vaccines have proven to prevent serious adverse health outcomes. In Washington State, unvaccinated 12-34-year-olds were five times more likely, and 35-64-year-olds were seven times more likely to be hospitalized with COVID-19 than vaccinated individuals. Additionally, unvaccinated people 65+ years are 11 times more likely to die of COVID-19 than vaccinated individuals. Thus, vaccines are necessary to protect the population from severe infection. From a CFD share stock trading standpoint, companies that make vaccines may be worth keeping an eye on over the long term.

Breakthrough Infections

Even though vaccines reduce the risk of death and severe illness, even highly effective vaccines are not 100% effective at preventing the infection. However, when vaccinated people get COVID-19, the symptoms are way less severe and often described as cold-like or asymptomatic.

For vaccinated people with symptoms, the symptoms typically include a cough, fever, headache, and sometimes loss of smell. The vaccine is necessary because it results in vaccinated people getting mild symptoms rather than potentially being hospitalized.

The Vaccines are Effective Against Most Variants

Several new variants of COVID-19 have been circulating throughout the world as the virus causing COVID-19 is constantly changing. The vaccines have proven to reduce hospitalizations and death against several variants. For instance, the vaccine protects against the Delta variant, which originated in India, and the Omicron variant, the dominant variant circulating in the US that originated in South Africa.

While it is uncertain how the vaccine will fare against variants that arise in the future, they are necessary because they have worked on the variants that have occurred so far. The CDC will monitor how effective the vaccine is against them when new variants arise.

When scientists discover a new variant, it generates uncertainty and causes share trading prices to experience volatility. However, given the effectiveness of the vaccines against variants so far, stocks like Pfizer and Moderna may move higher or lower, depending on the situation, which may present both opportunities and risks for CFD stock trading.

The Vaccines are Safe and Tested

Authorized vaccines like Pfizer and Moderna have gone through safety testing and evaluation before the Food and Drug Administration licenses them and they become recommended for use by the Centers for Disease Control and Prevention (CDC). Additionally, vaccines are continuously monitored for safety and quality after being recommended to the public.

The Bottom Line

Vaccines create an immune response to help the body fight off the infection. Vaccines are necessary to protect the population against COVID-19 for several reasons. First, vaccines effectively reduce the risk of death and severe illness from COVID-19. Second, vaccines have successfully reduced severe infection with multiple strains and will likely continue to do so. Third, breakthrough infections still occur even though these vaccines are highly effective. However, these infections are way less severe and are often described as cold-like symptoms. Finally, the vaccines are proven to be safe and have been tested before being distributed to the population. For these reasons, vaccines are necessary to reduce the severity and risks of COVID-19, increasing the interest into certain companies’ stocks for CFD share trading.
