10 things to know about the Novavax vaccine

In the search for immunization measures during the COVID-19 pandemic, several vaccines have been developed to boost immunity against the respiratory virus. Here, the Novavax vaccine is one of the options that has gained attention for its distinctive characteristics and potential to contribute to global vaccination efforts. So, here are a few things one should know about the Novavax vaccine, including its development and mechanism of action to eligibility criteria:

1. Vaccine development
The Novavax vaccine, also known as NVX-CoV2373 or Nuvaxovid, was developed by Novavax, Inc., a biotechnology company. The entity has previously worked on developing vaccines for various infectious diseases, including respiratory syncytial virus (RSV) and seasonal influenza.

2. Vaccine technology
The Novavax vaccine operates on a different principle than some of the other COVID-19 vaccines. It uses a protein subunit-based approach, using a small piece of the SARS-CoV-2 virus, called the spike protein, to stimulate an immune response. This protein fragment is produced using a baculovirus expression system, a well-established technology in vaccine development. This approach also involves the use of an adjuvant—a substance that boosts the level of immune response.

3. Authorization of use
The Novavax vaccine has received authorization in the country based on the trial data demonstrating the vaccine’s safety and efficacy in preventing COVID-19. Trials have shown that the Novavax vaccine can help prevent the disease and has demonstrated efficacy against multiple variants of the virus, including the Delta variant. In trials, it has shown efficacy rates of over 90% in preventing symptomatic COVID-19.

It is important to note that the status of vaccine authorizations may change over time with new developments. So, it is advisable to check with relevant health authorities or official sources for the most current information regarding vaccine authorizations.

4. Safety profile
Like all vaccines, the Novavax vaccine may cause side effects, but it has a favorable safety profile.

All About Age-related Macular Degeneration

All About Age-related Macular Degeneration

Age-related macular degeneration (AMD) is one of the top causes of vision loss in people aged sixty and older. It is a disease that hampers your sharp, central vision. Central vision is pivotal to helping you see objects clearly and do tasks like driving and reading. AMD impairs your macula, the part of the eye that helps you see fine detail. It is not painful, but it kills the cells in the macula. It starts with blurred vision, but you gradually lose central sight. Seeing crooked lines is one of the initial AMD signs. In this guide, we will discuss everything related to AMD in detail. Types of AMD Dry People with dry AMD have drusen or yellow spots in the macula. Small drusen might not necessarily impair your vision, but as they grow in size and increase in number, they distort and dim your vision, especially as you read. Over time the condition worsens, and the light-sensitive cells in the macula get thinner and die eventually. If it is in the atrophic form, you will experience a blind spot in the center of the vision. Consequently, it worsens, and you lose central sight. Wet Blood vessels grow below the macula. These leak fluid and blood into the retina. So, when your vision is distorted, the straight lines look wavy. It might also lead to blind spots. At times, the blood vessels may bleed, leaving a scar and causing you to lose your central vision forever. Typically, people with age-related macular degeneration have dry AMD. But, sometimes, the dry form might eventually result in wet AMD. Only 1 in 10 people with macular degeneration get wet AMD. When you have macular degeneration, you must see your eye doctor frequently and closely monitor your eyesight. AMD symptoms The AMD symptoms depend on the stage.

Tips to Manage Age-related Macular Degeneration

Tips to Manage Age-related Macular Degeneration

Age-related macular degeneration (AMD) is a condition threatening one’s eyesight and general health. In AMD, the macula, the part of the eye that helps produce the most detailed and sharpest vision, starts to break down and thin, resulting in vision loss. It is one of the most prevalent causes of blindness in people aged 60 or older. Though there is no definite cure for AMD, some things can postpone its onset or lower its severity. Being aware of family history Family history and genetics are one of the leading causes of AMD. So, if you have a first-degree relative with AMD, your chances of developing it are also higher. Hence, you must be vigilant and educate yourself on the potential AMD signs, such as the inability to adapt to low light conditions, difficulty identifying faces, and straight lines looking wavy. Knowledge of these symptoms can help you reach out to an ophthalmologist and get timely treatment while AMD is still in an early stage. Getting routine comprehensive medical checkups In the early stages of AMD, you might not experience any symptoms. Hence, routine comprehensive eye exams with an ophthalmologist can help with timely diagnosis and treatment. It holds even for adults 40 or older with no risk factors or signs because this is when you may develop early AMD symptoms or experience changes in vision. After 65, consider increasing the frequency of eye examinations and get one every one to two years, even if you do not have any suggestive symptoms. Taking supplements A study found that supplementation with some micronutrients can lower AMD aggravation from the intermediate to the advanced stage by approximately 25%. In the market, one can find several vitamins sold over the counter claiming to help with AMD or eye-related diseases. If your eye doctor finds yellow spots on the retina in the eye dilation examination, they may prescribe them.
