Top 5 Things to Know About mRNA COVID Vaccines & Rapid Tests

As the world enters its fifth year of managing COVID-19, the development of mRNA vaccines and rapid COVID testing continues to evolve. Innovations in these technologies have enhanced vaccine durability, broadened testing accuracy, and improved pandemic preparedness. Whether you are considering a booster shot or wondering how effective rapid home tests are against new variants, staying informed is essential.

With ongoing seasonal surges, Rapid Home Tests are a vital tool for staying healthy and protecting your family and loved ones. Stock your home medicine cabinet this season with market-leading ASSURE-100 rapid tests.

Here are the top five things to know about mRNA COVID-19 vaccines and rapid testing in 2025.

1. New mRNA Vaccines Offer Longer-Lasting Protection

mRNA vaccines have undergone significant improvements, with newer formulations providing longer-lasting immunity and broader variant coverage.

• In late 2024, updated mRNA COVID vaccines were designed to target multiple Omicron subvariants, such as JN.1 and XBB.1.16, offering better immune responses.
• Studies indicate that booster shots may now provide protection for 12–18 months, reducing the need for frequent doses (source).
• Research is underway for a pan-coronavirus vaccine, which could protect against multiple coronaviruses beyond SARS-CoV-2 (source).

2. mRNA Vaccines Are Being Tested for Nasal and Oral Delivery

Traditional intramuscular injections may soon be complemented by nasal spray and oral mRNA vaccines, potentially improving accessibility and effectiveness.

• Nasal vaccines aim to provide mucosal immunity, preventing the virus from infecting the respiratory tract at the source.
• Early trials suggest that oral mRNA vaccines could be stored at room temperature, solving cold-chain storage issues (source).
• If approved, these alternatives may reduce transmission and make vaccination easier for individuals with needle hesitancy.

3. Rapid COVID Testing Remains Crucial for Detecting New Variants

With new SARS-CoV-2 variants emerging, rapid home tests remain a vital tool for early detection and preventing outbreaks.

• Most FDA-approved rapid antigen tests still effectively detect Omicron subvariants, including JN.1 and XBB lineages.
• Multiplex rapid tests are now available, allowing users to test for COVID-19, influenza, and RSV from a single sample (source).
• The CDC recommends serial testing (two tests 24–48 hours apart) for the most accurate results, especially for individuals with mild symptoms.

4. Hybrid mRNA Flu-COVID Vaccines Are in Development

Combining flu and COVID-19 protection into a single mRNA shot is one of the most anticipated advancements in vaccine technology.

• Moderna and Pfizer-BioNTech are conducting phase 3 trials for combination flu and COVID-19 vaccines.
• Early data shows similar or better immune responses compared to separate flu and COVID shots.
• If approved, these vaccines could simplify annual immunizations and improve compliance among high-risk populations (source).

5. COVID-19 Testing and Vaccination Accessibility Has Improved

Governments and health organizations have focused on making vaccines and rapid testing more widely available.

• Self-testing kits are now integrated with smartphone apps, providing real-time result interpretation and tracking.
• The U.S. government has reinstated free COVID-19 test distribution programs, ensuring accessibility to at-home testing.
• Pharmacies and healthcare providers offer updated vaccines at no cost for eligible individuals, reducing disparities in vaccine access (source).

As COVID-19 continues to evolve, so do the tools to combat it. With more durable mRNA vaccines, advancements in nasal and oral delivery, improved rapid testing, and hybrid flu-COVID shots on the horizon, public health efforts are better equipped than ever to manage the virus.

Staying informed about these innovations and utilizing rapid home tests for early detection will help individuals navigate COVID-19 in 2025 and beyond. Whether through updated vaccines or new diagnostic tools, ongoing research ensures that we remain prepared for future health challenges.
