Your Sandbox
It is unlikely that what you have written in your Sandbox can become an article. All content in articles needs to be verified by references. Medical/health articles are held to a high reference guideline described at WP:MEDRS. Last but most important, COVID-19 vaccine already exists as a high quality, well-referenced article.
