Ideally, what I’d like to do is helping other people, so I’m volunteering at an old folks’ home.

I had been longing for a meaningful experience, and I finally found it there.

What I really loved about going there was talking about all sorts of things with the people I met.

Some had traveled a lot and others had spent their whole lives in my little town. Even so, all of them had gone on such incredible journeys, which included: raising kids, learning skills, and overcoming challenges.

To be honest, I’ve traveled to the far most corners of the world and been on the most incredible journeys, through the stories that my friends have told me, both young and old. It’s both peaceful and fulfilling and I wouldn’t trade it for anything, neither would my friends because they know I’ll always be here for them when they return…

1. Bảo quản vắc xin

Đây là một yếu tố đặt lên hàng đầu bởi vắc xin luôn đòi hỏi phải bảo quản ở một điều kiện nghiêm ngặt, đặc biệt là các loại vắc xin nhược độc. Mỗi loại vắc xin đều có một khoảng nhiệt độ bảo quản thích hợp, đối với các loại vắc xin virus ở nhiệt độ từ 2 – 8°C, các loại vắc xin vi khuẩn từ 5 – 150C. Nếu nhiệt độ bảo quản vắc-xin nằm ngoài khoảng nhiệt độ bảo quản, hoặc để vắc xin bảo quản ở ngăn đá sẽ làm mất tác dụng của vắc xin.

Ngoài ra, bà con cũng cần chú ý việc bảo quản vắc xin khi vận chuyển, nếu ở xa nơi bán vắc xin thì khi đi mua nhất thiết có hộp xốp, phích đá để bảo quản; nếu mua gần thì bảo quản bằng túi nilông tối màu có giấy bọc. Khi vận chuyển vắc xin cần bao gói kỹ, tránh hiện tượng va đập, tránh được vắc xin tiếp xúc trực tiếp với đá lạnh, đặc biệt không cho ánh nắng trực tiếp chiếu vào vắc xin để đảm bảo chất lượng và hiệu quả phòng bệnh của vắc xin.

2. Sử dụng vắc xin

Nếu khâu bảo quản tốt song chúng ta sử dụng vắc xin không đúng kỹ thuật thì hiệu quả cũng sẽ thấp. Khi sử dụng vắc xin chúng ta cần chú ý các yếu tố sau:

- Cần đọc kỹ hướng dẫn sử dụng vắc xin trước khi dùng, nếu không rõ thì hỏi thêm ý kiến của bác sĩ thú y.

- Khi dùng phải kiểm tra lọ vắc xin bằng mắt thường xem màu sắc, độ vẩn có gì khác thường (ví dụ: không dùng vắc xin bị đổi màu, vẩn đục).

- Không được tiêm vắc xin cho động vật đang mắc bệnh, nghi mắc bệnh, động vật quá gầy yếu, quá non, con mẹ mới đẻ, động vật mới thiến chưa lành vết thương, những con mang thai ở kỳ cuối.

- Dùng vắc xin đúng liều lượng, đúng vị trí, đúng lứa tuổi.

- Xi lanh, kim tiêm phải đảm bảo tiệt trùng. Biện pháp tốt nhất là luộc sôi hoặc hấp, để nguội dụng cụ trước khi sử dụng (chú ý không nên dùng cồn để sát trùng dụng cụ).

- Pha vắc xin đúng chỉ dẫn, trước khi sử dụng phải lắc kỹ lọ vắc xin.

- Vắc xin pha xong dùng ngay, không để quá 2-3 giờ sau khi pha, không cầm lâu trong tay; nếu thừa phải hủy, không được dùng cho ngày hôm sau; không vứt bừa bãi chai lọ, kim tiêm.

- Sau khi tiêm vắc xin, cần theo dõi vật nuôi để kịp thời phát hiện các trường hợp gia súc, gia cầm phản ứng sau khi tiêm để có biện pháp can thiệp.

3. Một số bệnh cần chú ý tiêm phòng cho vật nuôi

- Đối với trâu bò: tiêm phòng bệnh tụ huyết trùng, lở mồm long móng.

- Đối với lợn: cần được tiêm phòng đầy đủ 04 bệnh đỏ (tụ huyết trùng, phó thương hàn, đóng dấu lợn, dịch tả lợn), lở mồm long móng.

- Đối với đàn gà: tiêm vắc xin Newcastle, Gumboro, Cúm gia cầm.

- Đối với đàn thủy cầm: tiêm Cúm gia cầm, Dịch tả vịt.

Current students all have a phone. It is very useful in many ways such as: watching movies, contacting families when necessary, reading newspapers online without spending money, playing games or even talking, texting with friends when free time, shooting Beautiful photos to make memories with friends or family. But everything has two sides: the good and the bad. The phone also has a bad side. It makes us neglect studying, not hanging out with friends and sometimes even phone calls that make us not pay attention to listening to lectures, not concentrating, learning slipping. And the worst thing is that it makes us addicted. Always hold the phone with you when you eat, when you go to bed when you go to bed, when you go out and when you go to the toilet. If we use them, we have to balance learning, playing with friends, family, doing chores with the phone properly.
