Should I Bother Getting a Bivalent COVID Booster Now?

San Francisco Chronicle—Gladstone Senior Investigator Nadia Roan explains that while prior vaccination or exposure to COVID-19 may confer long-term protection against serious disease, a booster shot with the bivalent vaccine will protect you for a few months against new infection.

New COVID Subvariants Are ‘the Most Immune Evasive Yet.’ Here’s What That Means

San Francisco Chronicle—New SARS-CoV-2 subvariants are driving an increase in COVID case numbers around the world. Gladstone Investigator Nadia Roan explains that the subvariants have mutations that help them evade neutralizing antibodies, but stresses that getting the bivalent vaccine can still help strengthen immunity to the ever-changing virus.

How Long Does Immunity from the New COVID Bivalent Boosters Last ’in the Real World’?

San Francisco Chronicle—The new bivalent COVID-19 booster shots are recommended for individuals age 5 and up who are at least two months past their last vaccine dose. Gladstone Investigator Nadia Roan explains that the bivalent boosters greatly increase the levels of antibodies that can prevent the Omicron variant from infecting cells.

Omicron Subvariants BA.4, BA.5 Are Spreading ‟Like Wildfire”, Becoming Dominant Strains in US

ABC7 News—As Omicron BA.4 and BA.5 variants overtake previous coronavirus variants across the United States, Gladstone Associate Investigator Nadia Roan, PhD, explains that their success may owe both to their ability to escape our immune system and to their accelerated replication rate. She suggests that more effort should be made to block infection at the level of the airways, the virus's entry point into our body.

Fever, Body Aches, Loss of Smell: New COVID Study Charts Evolution of Symptoms

San Francisco Chronicle—A study in the Mission District of San Francisco tracked how COVID-19 symptoms have changed over the course of the pandemic. Gladstone virologist Nadia Roan explains that the Omicron variant infects the upper respiratory tract and triggers a localized immune response, which may in part explain why individuals infected during the Omicron wave were less likely to experience severe illness.

Scientists Explain Why Getting Infected With Omicron Doesn’t Protect You From Other COVID Variants

ABC News—Gladstone virologists investigated the effect of the Omicron variant on the immune response. Melanie Ott describes her team’s discovery that previous infection with Omicron does not result in strong immunity to other known SARS-CoV-2 variants. However, as Nadia Roan explains, individuals who were vaccinated before becoming infected with Omicron did have a broadly protective immune response, emphasizing the importance of the vaccines in saving lives.

Omicron Could Be the Beginning of the End of the COVID-19 Pandemic

Time—The Omicron variant of SARS-CoV-2 has spread around the world at an alarming rate, but some scientists think the variant might actually be a sign of hope. Nadia Roan explains that widespread infection may lead to widespread immunity, which could help turn the pandemic virus into an endemic virus. Warner Greene posits that the best-case scenario is that the virus will weaken, continuing to spread but without causing severe disease.
