What was conclusion of Edward jenner in case of small pox?</h3>
He also came to the conclusion that small pox may be passed from one person to the next. Edward Jenner came to this conclusion based on stories he had heard about dairy maids being immune to smallpox.
In 1736, Edward Jenner met Sarah Nelms, a young dairy girl with small pox lesions. Edward Jenner then vaccinated an 8-year-old kid named James Phipps with material from Nelms' small pox lesion. James Phipps suffered a fever and became unwell, but he recovered completely after ten days.
Jenner infected the same boy with materials from a fresh small pox lesion a month later. There was no sickness in the boy.

The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells called keratinocytes.
<h3>
What is keratinocytes?</h3>
- Skin cells, also known as epidermal keratinocytes, are highly specialized epithelial cells created for a very specific purpose: separating the organism from its environment.
- Keratinocytes, which make up the majority of the epidermis, have a variety of functions that are crucial for skin restoration.
- They carry out the re-epithelialization process, in which keratinocytes move, multiply, and differentiate in order to reestablish the epidermal barrier.
- The majority of the epidermis's cells, known as keratinocytes, begin in the basal layer, manufacture keratin, and help to create the epidermal water barrier by producing and secreting lipids.
- A kind of stratified epithelium known as keratinized stratified squamous epithelium has many layers of squamous cells, or keratinocytes, with the superficial layer of cells being keratinized.
- The skin's epidermis is made up of this kind of epithelium.
